Help Me Please! Climate Control Problem!
Please somebody help me! LOL, i have a problem with my climate control. The blower fan speed always operates at high speed, no matter what the display on the climate control is set at. Once and awhile the fan will go down to the proper speed, but only for a short time. If anyone has heard of this or has any ideas, please contact me. email: bigpoppapumpjml@hotmail.com

first look at what controls it... the ****. remove the **** and test it for resistance and functionality V/S resistance as you rotate it. Also, see if the control will work manually without the ****.

Also, did you confirm the brain is original, like suggested in the other thread? That does cause known issues.

I dont really know how to check the brain, it appears to match, but dont know for sure.

Does the fan speed change if your in manual more often? It may actually be the temp sensor like OLT mentioned for another thread. I am more inclined to think temp sensor or the relay, before the brain.
What year is your coupe and where in IL are you?
I have a spare fully functional 92 brain which you can try - no lcd front attached, but it is plug and play. Plenty of threads abound on how to take it apart.
Im in Terre Haute

Geez, this town is the pits... anyway.
