Lost controls for heat and air

[Below Average Joe]

All. I have a 2003 GT and have lost the controls for the heater and the air. 1 hasn't worked for years, but this morning on my way home i heard a pop then nothing. It won't turn up. Other than the fuse, what could be the problem? I haaven't checked teh fuse becasue it is cold outside.

It should work on 5 at least unless its a fuse or blower motor.

Does not work on any setting. I have never heard a fuse pop that loud which make me think it is something else. Where is the blower motor?

 

[dsmuts]

under the glove box. Hit it with your hand and see if it does anything. If not check your fuse.

I imagine that is what it is since the poping sound came from that side of the car.

 

[dsmuts]

Let us know what you figure out. It's warming up outside now, not much though.

i have to leave in an hour and a half so I will try it then. If smacking the glove box area doesn't help i will check the fuse tomorow since I will have a place in a garage that is warm. Thanks for the help. I will update probably Monday.

There will be a piece of carpet on the underside of the glove box and you'll have to remove that to see the blower motor. Give it a good whack with your hand and see what it does.

So, Saturday afternoon the controls still did not work after giving the motor a smack. About 10 minutes into the trip I turned it to 5 and nothing, but 2,3,4 now work, but 5 still did not. On Sunday nothing worked againt the first but after turning to 5 then back the 2,3,4 worked again and this time 5. This morning the same thing. I am going to check my fueses on lunch, but I have noe lost the windshield washer control. I know it does freeze in Ohio during winter, but it still gives a humming when it is working, but now nothing. I will know more after I check the fuses, but i am going to guess the fuses are fine.

Blower sounds like some sort of electrical short. Maybe a bad resistor or ignition switch?

I have heard of the resistor being bad and the key won't come out from time to time. I just press the button under the column to remove the key. Where is this resistor?

 

[dsmuts]

the resistor is right behind the blower motor. You'll have to lay upside down in your pass seat to see it. I've change a couple they really aren't that bad.

Everything works again?!?!? The only thing that doesn't work is setting #1 and that hasn't worked for quite some time. Thanks for the help.

 

[dsmuts]

don't worry it'll break again one day lol they always do

I imagine it will be sooner rather than later, but that comes with owning a Grand Prix or a GM product for that fact.
