Climate Control System Problem

I have an intermittent problem with my 2001 DHS Climate Control System. Occasionally, when I start-up, there are loud rattling, clicking type noises from the dash board behind the climate control panel as the system begins to kick in. The noises stop if I shut the system off or cycle the system manually with the "mode" switch to ventilation options other than the "auto" mode. Is this a known type of problem? How do I take the climate control panel off to get a look at what is going on? I would take the car in to someone, but the problem is intermittent.

    Yes, That was the problem with my 2002 Deville. I spent a lot af money changing the blend door actuator then only a/c turned on the Driver side no matter what the setting was. What now???

The noise is most likely coming from a sticky temperature control blend door, ( they warp from heat, not an un-common issue) it is moved with a electric actuator. This is very expensive to fix, requires removal of the dash to repair, if the system works ok then if it was me I would "live with it".

Check engine light comes on intermittently,


the 1st thing u need to do is have the system computer tested for trouble codes, anytime the light comes on a trouble code is stored, there are over 200 of these codes for potential system malfunctions, yours sounds like a O2 problem.

this system has self testing capabilities, have any GM dealer test it for codes and proper function, If I had to guess I would say the climate control head is defective.

Climate Control


The electronic climate control is much more elaborate as you would expect and I see many more power connection points. These might be empty fuse sockets on your model. The factory would have installed only what was needed for the basic A/C.
Same with the Mach 460 system. The basic audio system with amplifier does not even include a separate plug-in for a sub. You might be able to get some degree of functionality but not without a lot of extra work.
