Yo Seth,
You have a 93, correct?
You could just have a tired motor or a bind, lowering the window is easier than raising it sice you have gravity working for you going down and against you going up.
I would try jumpering the motor direct by disconnecting the plug and putting 12V directly on the pins to the motor, swapping the leads will change the direction of the motor. So if it is up and nothing happens, swap the leads and it should go down. Then swap the leads and see how well it works. If jumpering it direct still exhibits the same symptom, then:
First check for a bind in the track. A worn regulator mechanism often causes the window to bind when going up. It causes the window to shift and try to go up at an angle insted of strait. If that is OK then:
Second remove the motor and check the condition of the gear. If it looks good, then you probably have a tired motor.
However, if the motor works just fine when jumpering it then you have a wiring problem.
The problem could be the ground path which originates on the driver side and then goes to the passenger side. It goes thru two flex points where the wires transition from the door to the body and back again to the passenger side. Wires in those areas tend to break but they don't break all at once, they go strand by strand which gives a high resistance path for current to flow thru and causes the motor to be sluggish and first noticable in the up direction.
One assumption I have made for the above proceedure is that if the problem is with the Passeger side window and you have the same symptom from either door control. If not, then the +12V path is to that particular window is suspect

B1 DETERMINE INOPERATIVE WINDOW
Is passenger door window inoperative?
B2 CHECK INOPERATIVE WINDOW POWER SUPPLY
- Remove left window regulator control switch per outline.
- Using test lamp, connect lead to a known good ground.
- Using chart below, connect test lamp to appropriate circuit.
- Actuate window regulator control switch in appropriate direction and observe test lamp.

- Gain access to inoperative window regulator electric drive connector as outlined.
- Disconnect window regulator electric drive connector.
- Connect test lamp lead to a known good ground.
- Using chart below, connect other end of test lamp to appropriate circuit.
- Actuate window regulator control switch in proper direction and observe test lamp.

B4 CHECK CIRCUIT CONTINUITY
- Disconnect left window regulator control switch.
- Using ohmmeter, check resistance of suspect circuit between harness connector and left window regulator control switch.
| Yes | No |
|---|---|
| GO to B5. | SERVICE open circuit. RESTORE vehicle. RETEST system. |
- Using a jumper wire, connect one end to battery positive, connect other end to Pin 1 at window regulator electric drive.
- With a second jumper wire, connect one end to a known good ground. Momentarily connect other end of jumper wire to Pin 2 of window regulator electric drive.
- To reverse window regulator electric drive direction, switch jumper leads at window regulator electric drive.
| Yes | No |
