Thanks for the input, Larry & Ali!
My climate control is still making noise and seems to be getting worse. It does still blow cold air, but I'm afraid of making the situation worse by using it. A vibration can actually be felt, especially through the accelerator. I have checked for TSBs on AlldataDIY, and there is one listed (Job #83-510 and 512) about noise coming from the compressor and it states to check the function of the Expansion Valve.
Unfortunately, I know very little about air conditioning/climate control systems, however, I live only about 40 miles from Gainesville, Florida. As such, I believe I will take my car to Steve Brotherton's Continental Imports and let them look at it for me.
Thanks, again, for your help and information!
