It's possible that your heater core is plugged up. It can also be a bad thermostat.
yes 1987-1994 will work
Remove the trim work like around the doors... the headliner is mainly held up and on by the trims and also the visers
Because it is an Dodge. GET A CHEVY
2001 dodge ram 1500 ac and heater flow regulator switch does not work. works only on defrost. How to fix?
replace heater core in a 1991 Chevy work truck 1500
yes if it stuck open.
Heater coil could have went out.
Maybe because your climate control system needs to be repaired....
Blown fuse, defective blower motor, defective wiring, defective blower motor resistor pack, or in rare instances a defective blower motor speed control.
Just removing one engine and putting it into another car IS major work!!! But to answer the question without being a smart-ass, there are 2 turbo motors available from a 1991 Spirit, a 2.5 turbo and the truly awesome and rare 2.2 turbo III. The Turbo III has too much torque for most automatic transmissions so you'd also have to replace the transmission to the high torque 568 manual trans. There, you now have more work to do now. That means adding the right pedals to the car. More work. You'd have to use the computer from the Spirit with the Turbo III car and the engine wiring harness. Still more work. Want an easier way to do this? Put the 1993 grill and tail lights on the 1991 car and drive it home. Faster than you drove the 1993 there, of course!
The sending unit may be faulty
Start out by checking that the blower has both power and ground and if so then next check the a/c - heater controller...........
