You can check the fuse panel for a blown fuse. Replace blown fuses with the recommended fuse only. Its not safe for your car or you, to switch them to a different size. Be sure that your ignition is in the off position and take the keys out before you change any fuses. If its not a blown fuse, you could have a blown fan motor or faulty wiring but I'd start with the fuse box.

SOURCE: blower vent selector switch not working

this is what is called a factory default. for safety purposes if there is a problem with the wiring in the climate control system it defaule to the defrost position so you can see out the window. this can be a pretty tough job, the whole dash may have to come off. unless you well versed in automotive diagnostics and troubleshooting, and have the right equipment, I would take it to a local automotive technician.

Heater and ac sometimes won't work til i drive for awhile


Many of those type trucks have a fuel gauge issue...I don't think it is in relation to your heat and cool problem...I know people have had to change the complete fuel sending unit assembly to fix gauge...It wasn't cheap...Should have been a recall but it wasnt...However I don't have enough info for the heat/cool problem...Is the blower motor running all the time or does it not run until you drive for awhile..?..Some blower motors that go bad won't come on until they are jarred or tapped with a hammer...Maybe it is vibrated while driving and finally comes on...You have to listen closely to make sure if it comes on when you turn it on...If it always turns on when you flip the switch then it sounds that your HVAC blend vent doors are very slowly opening...This could mean the door actuators are wearing out or the plastic vent doors are contaminated at the hinge and slowly opening.......So check the blower motor operation first...If it don't blow until you drive the motor is going bad...First make sure all fuses have a good connection..sometimes they vibrate out...Also blower motor relays.If a blower motor relay is bad the blower will not come on at all....A faulty relay will not work the fan at all....If the blower motor comes on when it wants to it has to be a bad motor or improper connection....Sometimes a motor will operate but doesn't blow..This could mean the fan has torn loose from motor....Best way to troubleshoot blower motor is remove it,inspect fan connection...,hold it safely in your hand while an assistant turns it on.....Good luck..

Blower works but not getting full air force


If the blower is not producing a strong flow of air, something has to be restricting it. Or something simple like the blower cage is slipping on the motor shaft.
You disassembled the HVAC box, are you sure the heater core or evaporator is not stopped up? Or the intake vent ?

Vent blower not working


If you are talking about the blower for the heat and ac, someone needs to check the blower for voltage and ground, also the blower relay and the resistor as needed.

OK. So the blower notor isn't operating. Do you have power to the blower motor? The resistor is new from what I got. If you don't have power to the blower motor, then check the speed control switch and fuses. If you have power at the blower motor, replace the blower motor

on the front blower make sure the fuse is ok if it is then check the relay if its good as well then youll ned to replace the blower motor. as far as the rear it sounds as if the air handler is not operating properly you need to locate it and ensure that nothing is blocking it from turning.hopes this helps you.

Heater blower


Sounds like the blower motor resistor is bad. These things go bad all the time. and for the switching modes there is a vacuum line that runs under the window in the engine compartment and runs by the alternator, its tiny and may take a few minutes to find. check first by the evaporator case and follow it by the alternator to the driverside of the throttle body. these too break and will not allow the heater mode changes. the blower motor resistor controls the fan speeds and the vacuum line allows which vent the air flow goes through.
