AboutSkip Bollinger Expertise Heretofore, I will NOT answer any mechanical question. I am not qualified and can only offer speculations. You are better served by others that are true Techs. With that being said, please only ask about parts and locating obsolete Auto Parts. Thank you.
I have the ability to locate quite a few mechanical parts for American made vehicles fron the 1900`s to present. Some are OEM and some are aftermarket. This would include engine, brake and chassis parts. Body parts and trim are VERY difficult to find but you may inquire.
If you need assistance in repair, I have illustrated books for major American manufacturers that show some illustrations BEFORE 1974. If needed, I can supply repair manuals for your specific vehicle.
PLEASE REMEBER I'M A PARTS SPECIALIST, NOT A TECH!! Thank you..

Question I hear a loud click when I rotate the funtion button to the defrost position, however if I move it back to just blowing air in the cabin the sound goes away.
I am not sure if they are related but I remember last summer hearing a similar noise while turning the A/C on and off.
I just replace the resistor for the blower and this doesn't fix it.
Is it the compressor? Blower?
Thanks

I am a Parts Specialist, NOT a Tech but will off these thoughts for you to ponder.
Your mail is a bit confusing. At first you say you hear a "loud click" when you place the selector in the "defrost" position. Then you say that when you move the selector to "just blowing air"..."the sound goes away". One statement leads me to believe the noise is momentary and the next statement leads me to believe the noise is ongoing. I'm confused. Regardless...
I'm going to guess the noise in in the diverter door area under the dash. From the information you have provided, it has nothing to do with the compressor or blower. You may have to get on your back on the front floor board to pinpoint the noise. You may need to have someone else move the selector while you listen for the noise.
I'm sorry I'm NOT a Tech. IF I'm wrong, don't hammer my chops. I'm just trying to give you some direction. This is something that can be expensive to repair. It isn't the price of the part but the time it takes to get the dash apart to get to the part. Good luck...
