Hello,

I'm having some trouble with my climate control system. The blower motor is not kicking on when I select defrost or in any other settings.

When I select defrost setting, I hear a click at the front of the engine comparment. Sounds to be near the AC compressor

The push button control unit was replaced a in 2001. What could be causing the problem?

Thanks in advance,
mar300sd

But what year? Is this the year with the ACC Servo mounted on the passenger wheel well?
