98 Deville Blower Motor

[brianroark]

I have a 98 deville with the blower motor non functional. I used my multimeter to test the connector going to the blower motor. On the black wire I have a constant good ground, Red wire has 12 volts. The middle signal wire has 0 volts. I tryed jumping the middle wire with 12 volts thinking 12 volts might not do anything but with a loose connection it might see 3 volts for a sec and spin just a tad. my thoughts were for high speed it needs 3 volts and low speed 12 volts. still no blower motor. I also have a low refridgerant light on the dash board. I'm thinking its the a/c programmer. Does this sound like the problem? I know on my car i had a problem with the power control module but someone told me this blower motor has it built into the blower motor and i have 0 volts non changing through cycles on the middle white wire.. what possible things could it be? any relays that could be causing the problem with a good supplied 12 volts to the red wire? Its my dads car and he cant remember if he had the low refridge light on before or not.. also on a side note his seat moves once in awhile i think that could be a different problem all together? i dont really think its the body control module because everything else works in the car.. can someone please help me and give me a few tippers. I'd like to approach this in a low budget approach. thanks much. I was also wondering if possible, could i get a 3 volt resister or something to drop a hot wire from 12 volts down from radio shack to bypass the a/c programmer if thats the problem.


in addition i hooked up a gm tech 2 to the care and send the motor in to a commanded blow and still no blower motor...

I have 94 Concurus, changed the A/C blower motor 2 months back and again I have the blower problem
I have to tap with a stick on the blower so it starts and after some time it stops again. I do not want to stop while I am driving and hit the blower.
I removed the power supply switch from the blower for now till I find a solution
I leave in a very hot climate in the middle east, these days it reaching 41-45 degree Celcius.
I have a warranty on this part but lost the invoice printout
My car Mechanic have good relation with the dealer part salesman and said that he will try to check with the parts salesmen, I hope I get the replacement.
in the mean time I am looking for an alternate solution and I desperately need a solution.

My Mechanic informed me that the Blower is close to the Engine head so the problem comes up due to the heat of the engine in this model.

I had a similar problem with my 95 Eldorado a year ago. The dealer said it was the climate control module next to the instrument cluster. A replacement fixed the problem. However, two days ago the blower did not go on. This morning it did. I hate to think I need another module. As I recall it was $300-400 to replace it. Time will tell.
