SOURCE: 1998 grand prix gt blower motor stays running even

The blower should stay on for about 5minutes to cool the engine off. It isn't a problem unless it is running continuously after the engine is cooled.

Had to jump start now heater/ac wont work, no air blowing


Check the fuse & relay (owners manual will show you where the box is)
Relay box in under the hood on the driver side just above the tire.
Inside fuse box should be on the side of the dashboard (driver side) very close to the door hinges.
I'm pretty sure you popped a relay or fuse during the jump.

You can pull the possible bad relay out and grab another relay (borrow it) from something else like brakes or lights.... just make sure it's the same part number.
(don't use fuel or engine control or anything that would stop the car from working)
Swap them and start the car to see if the AC/blower is working.

Hope this helps

The heater stop working a couple days after i added a radiator cleaner and the heater stop blowing warm air today, is there a fues to replace or did the heater valve get clogged


If the fan wont blow air at all then it is a fuse. If the fan works and the car is warm you have a clog somewhere. you could try pulling a heater hose off when the car is cold to check for flow.

My 99 dodge intrepid heater control stays blowing and wont light up and wont stop blowing unless i pull the fuse and nonew of the controls work


Are the different speeds working on the blower or is this stuck on just one speed ??? It seem as if the relay for the blower is fused together in the on position an can no longer be controlled by the switch. If this blower is not a relay controlled unit then most likely the blower switch is no longer working.

My 1988 chevy silverado blows the heater/ac fuse when engaging 4w


There is an electric actuator on the front axle that engages 4WD. This part commonly fails resulting in no 4WD. Unhook the electrical connector to this part and see if heater still blows fuses. If It does not blow the fuse, the problem is in the actuator. If it still blows the fuse then it could be in the wiring. Buy a repair manual and trace the wiring schematics.

91 Cavalier 4cyl AC Heater fuse blows


Disconnect the battery and do a continuity check from the heater fuse to ground. It will probably be a short. If so do a physical check of the wire(s) from the heater to the fuse. Look at any place where the wire(s) bend and any place where it's possible for the wire to vibrate against metal even if you have to cut tape and pull it out of a bundle to follow it, retape it later. I have faith in you finding a burned wire, good luck.

Blower wont turn off


If you turn the key off and it wont shut off the heater then there are some interesting things you need to check. The first would be the whole ignition switch. When you shut off the key, the power should stop to that accessory. If that is okay then you need to check the controls for the heater. The issue with no heat is one of a blend door being stuck and this could be the controls again.
