Yo brittinghamkevin,
The blend door, aka Temperature Control door is Cable operated.
B5 CHECK TEMPERATURE CONTROL DOOR OPERATION
Rotate temperature control knob from the full cool position to the full warm position and check operation of the temperature control door.
Does the temperature control door operate correctly?
Yes CHECK drive belt for proper tension or signs of slippage and wear. REPAIR or REPLACE as necessary. RETEST system.
No CHECK temperature control door for a binding condition. Also CHECK the A/C temperature cable for connection to the temperature control door and A/C control. REPAIR or REPLACE as necessary. RETEST system.
By placing the function control knob (18519) in the VENT position, the climate control system operates an air door within the heater air plenum chamber (18471) that directs outside air through the A/C evaporator housing (19850), into the heater air plenum chamber and out through the registers located in the instrument panel (04320). The volume of air discharged through the instrument panel registers can be controlled by the heater blower motor switch (18578) and temperature can be controlled through the temperature control knob.
Miesk5 Note, in our 96, since new, always felt warm air when knob is in cool position. May need to install a cable operated shut off valve in heater core hose or a Jeep Heater core bypass control valve such as what 88rustsurvivor,
moody, and Ditch Baby did at http://www.fullsizebronco.com/forum...orum/23-technical-write-ups/133340-install-jeep-heater-core-bypass-control.html
"...It's pretty easy to pull the panel out a little & inspect behind it; & If you can pull your radio out, you can look at the top of the A/C controls. Sometimes a wire from the radio gets tangled in the mechanism, and it can lock it. Or, the cables that connect the slides to the blend doors can kink or come loose. It's most common for the cable to pop out AT the blend door lever, over the passenger footwell, but that never locks the control, so it's probably not what happened in yours...." by Steve

Blend Door Location in a 94; 80-96 similar; "...Probably the temp blend door is loose & flopping around on its own. The easiest way to see it is to fully lower the glove box, pull the ~8 screws from the heater core cover, & look inside to the L (driver's side). You'll see the cable & control lever (in top L of 2nd pic) as soon as you fold the glovebox down, so inspect it first.

Temperature Control
Temperature is controlled by a manually operated air blend door in the heater air plenum chamber (18471). When the temperature control knob is in the extreme COOL position (fully counterclockwise) all air bypasses the heater core (18476).
When the temperature control knob is moved to the extreme WARM (fully clockwise) position, all air is directed through the heater core. When the temperature control knob is between COOL and WARM (between full counterclockwise and clockwise), air is directed through and bypassing the heater core in rough proportion to the position of the temperature control knob between the extremes of its travel.

NOTE: When the battery (10655) has been disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module (PCM) relearns its adaptive strategy. The vehicle may have to be driven 16 km (10 miles) or more to relearn the strategy.
Connect the battery ground cable.
Andrew asked his question because; "The air handling system is designed to provide defrost when no vacuum is applied to any of the three air door vacuum control motors (18A318). This is done to prevent a situation where defrost cannot be obtained due to a system vacuum leak. Instead, a leak in the vacuum control circuit will send all airflow to the defroster outlets. This condition may occur during acceleration (small leak), may exist at all times (large leak) and may happen only when certain specific functions are selected, indicating a leak in that portion of the circuit.
The vacuum hoses used in the passenger compartment control circuit are constructed of polyvinyl-chloride (PVC) plastic material. The vacuum hoses used in the engine compartment are constructed of Hytrel. Because of the materials used, the vacuum hoses should never be pinched off during diagnosis to locate a leak. Use Rotunda Vacuum Leak Tester 014-R1054 or equivalent to locate vacuum leaks. A wood golf tee can be used as a plug when it is necessary to plug one end of a vacuum hose for leak test purposes. "
Low or No Heat/Air Conditioning, High Effort to Turn Temperature Control Knob, Poor Temperature Modulation TSB 96-13-7 for 92-95 Bronco, F Series, F-47

LIGHT TRUCK: 1992-1995 BRONCO, F-150-350 SERIES, F-47
ISSUE: The temperature control knob may be difficult to turn on some vehicles. There may also be a low or no heat/cooling condition accompanied by poor temperature modulation. This may be caused by the single cable temperature door operating system being used.
ACTION: Replace the A/C Temperature Control Cable Assembly with a new pull/pull cable design. The new design cable will provide improved control of the temperature door. Refer to the following Diagnostic and Replacement Procedures for details.
DIAGNOSTIC PROCEDURE
1. If the vehicle exhibits high effort turning the temperature control knob or poor temperature modulation, a new cable must be installed. Refer to the Replacement Procedure listed in this article. For a low or no heat/cooling concern, continue on with the Diagnostic Procedure.
2. Check vehicle's coolant for the correct level, concentration and operating temperature with the thermostat open. If a concern is found in one (1) of these areas, refer to the appropriate Service Manual for repair procedures. The repairs must be done before proceeding.
3. Verify proper A/C system charge and operation. Repair as necessary.
4. If the concern still exists, perform the Cable Adjustment procedure listed in the appropriate F-Series/Bronco Service Manual, Section 12.
5. If the concern still exists, replace the temperature door cable. Refer to the following Replacement Procedure for details.
REPLACEMENT PROCEDURE
REMOVAL
1. Remove glove compartment and module assembly, if present.
2. Detach cable from plenum using Tool D91T-18532-A. Remove and discard cable.
3. At the cable bracket on the plenum heater core cover, cut away the bracket using a hacksaw blade or similar tool.
4. Remove the 5/16" headed screw from the top of the cam. Discard the cam and screw with spring clip.
5. At cam post, add post extension and secure with the new screw, torquing the screw to 1.7 N-m (15 lb-in).
6. Remove the upper left screw securing the plenum heater core cover and install the A/C plenum chamber support bracket between the ribs to the right side of the bracket which was cut off. Make sure the hole from the previously removed screw is lined up with the hole in the plenum chamber support bracket.
INSTALLATION
1. At the plenum chamber, move the temperature door arm to the "full warm" position (counterclockwise) and be sure it remains there throughout the installation procedure.
2. At the small end of the cable (control head), remove the temperature control bracket from the cable by releasing the three (3) snaps using Tool T94P-18532-A or a thin blade screwdriver to allow the cable to be pushed back through the instrument panel toward the control head.
3. Be sure the new pull/pull cable is in the "full warm" position. Check the molded-in arrow at the control head portion of the cable. Normally the cable is shipped in the "full warm" position.
4. At the plenum, position the cam end of the cable over the post. Make sure the temperature door arm can move into the slot of the cam and push down until the cam is engaged on the post. An audible click can be heard. If it is necessary to remove the cam cable head, use moderate finger pressure on the plastic tab at the top of the cam cable head, moving it back so the cam may be pulled out off the post.
5. Place the twin cables in the center slots of the A/C plenum chamber support bracket. If adjustment is needed later, the cables can be moved to the other adjacent slots.
6. Route new cable through the instrument panel following the same path as the old cable.
7. Check the new temperature control bracket to be sure it is in the "full warm" position. The tab should be in the slot in the bracket.
8. Push the temperature control bracket onto the control assembly and turn it to catch under the retaining tab. Secure with the new screw previously saved.
9. Place the knob on the temperature control.
10. Push the cable head onto the temperature control bracket (make sure gear pilot centering hole is lined up correctly) until the three (3) lock into position (you should hear a click of three (3) tabs).
11. Install temperature control assembly in instrument panel.
12. Swiftly rotate temperature control knob to each extreme (cool-warm) and listen for the sound of the temperature door closing in both directions. If no audible close is heard, move the cable into different slots at the A/C plenum chamber support bracket covered in Step 4 of the Installation Procedure until there is an audible close in each direction.
13. Bring vehicle to operating temperature and verify proper heating and cooling by measuring the temperature of the discharge air at the outlets.
14. At A/C plenum chamber support bracket, secure cable to bracket with a tie strap to keep cable in place.
Obtain an Authorized Modifications Decal and list the date, dealer number, and summary of alterations performed. Select a prominent place adjacent to the Vehicle Emission Control Information Decal suitable for installing the Authorized Modifications Decal.

Yes, 80 through 96 are similar; "...The easiest way to see it is to fully lower the glove box, pull the ~8 screws from the heater core cover, & look inside to the L (driver's side). You'll see the cable & control lever (in top L of 2nd pic) as soon as you fold the glovebox down, so inspect it first. The 3rd shows the whole cover - it's the large section in the top center with tiny white numbers inked near its bottom edge. The cables are visible, too...." by Stephen
