hey guys, yall helped me out before so now i'm returning with another issue... for starters, it's a record cold winter here in oregon and my heater fan decided it doesn't want to blow properly...phrasing... anyway, it used to sweat me out going down the freeway wearing a t-shirt in the dead of winter, now it barely pumps out any air at all. recommendations? i had a leak problem in my heater core and put some stopleak in my radiator and it quit and will defrost/defog my windshield and that's it, and it takes at LEAST 15-20 minutes.

not sure what yr truck you have as it doesn't specify in your post or profile
will be very helpful in giving you proper advise
but the heater blower is controlled by the switch and a resistor
most times if the resistor fails you have high speed only(direct voltage)
I would check the blower motor resistor first after I checked fuses
again not sure what yr you have
resistor are usually easy to get at and remove, pull it out and check resistors on back of resistor assemble
switch could also be faulty,blend door or vacuum issues too
