I have a 92 Bonneville SE. It has ***** to control; fan speed, temperature, and air placement. I have replaced the blower motor. The fan will work on the first three settings on the switch, but not on the fourth or "high" setting. I also have a problem with low air flow through my vents. All vents seem to flow evenly.

I am wondering how to remove the control switch, without damaging the dash panels also. Do they just pop off?

Thanks

Just wondering, did you check or change the blower motor resistor? Pretty sure that car has one, should be close to the blower motor.

Your air flow might be restricted because of an evaporator core being plugged. Check this out.

On the manual (your version) of the climate control the high speed is controlled by a relay. Basically direct to the battery voltage.

I changed the blower motor, but haven't tried the resistor. I'll have to give that a shot this weekend.

Work all week....... means I'll have to try all of these this coming Saturday. Thanks to you all for the info

Think relay, not resistor.

THANKS BILLBOOST37 your answer was dead on. Thanks to Eric, and Kevin also. I replaced the resistor, cleaned the evaporator core too. The cool is blowing on HIGH now thanks to my last part installed..... the Relay :o) glad to have the wind blowing again.

You are welcome! I'm glad you got it fixed.
