in search of 7 prong blower register for my 1985 Buick Riviera

[BuickGirlFromMars]

Thank you very much, I will have some test made to see if this is the problem, it could very well be.

is your blower not working? You still havent told us what its doing. There is a relay on the AC case that is separate from the resistor
Thats the one that if it sticks the blower motor stays running, I believe but if you have no power then maybe its stuck the other way.

the blower would continuously even with the car off therefore draining my battery

I called Parts place and it was not the correct part. I am determined to find it but as for now I am going to hook up some kind of switch to at least turn the blower on with the capability to turn it off as well. That was the main problem I was having with it was the blower would not turn off and causing my battery to drain.

I would say the one that Buick Girl pictured in her post is the one. It is a precursor to the blower module GM used in the 90's and like the one I pictured in post #7. I have replaced the one in my 98 Riviera twice in the 19 years I have owned the car. The very common failure mode is the blower stays on when you shut the engine down. They are expensive parts, 100.00 +.

Larry thank you once again and I will let you know how everything turns out

Now, I dont know for a fact this is going to work, but it works on regals, is the same shape, and I would think the controller in a regal is probably the same as the riviera. The C68 climate option is a rare thing to find in 1980s vehicles, let alone survivors, let alone just how many brand new ones there were. So this appears to be the only reproduction i can find. the module is redesigned so the prongs arent on top of it(water damage and corrosion common)

1985 Riviera Electronic Climate Control Issue place I found the info I posted

before replacing it: Do you know your resistor is dead? This is a lot of money for this part, so you would want to be sure. Most resistors when they die will work on full speed but nothing else

thank you very much for the info
