I got my new heater motor, switch and resistor in the mail. When I do the replacement, would it make any sense to remove the A/C parts while I am in there? This old car hasn't had A/C in years and I am never planning to fix it, nor am I planning to sell it. So... is it worth removing 50 lbs (or however much it all weighs) from the car?

The condensor's in front of the radiator, so you'd be disassembling a whole new area to remove it. The evaporator's above the blower motor, so you don't need to go there, either. Neither is terribly heavy.

The compressor is heavy, but it carries one of the rubber V-belts that drives the power steering pump: if you remove the compressor, you have to install at least a bracket and pully to hold the belt so the PS pump will continue to function. One or another of the aftermarket sources sell such a bracket.

My son and I had this opportunity years ago when the A/C gave up on his 1988 245, and we just left the compressor in place. In a 3000+ lb car, the additional weight of the compressor is pretty minor.

I agree that the weight is inconsequetial. Also please remember that "never" is a long time. I have seen many people who said they would "never" get their A/C going again change their mind after a sweltering summer or a job change that required one to be un-sweaty and well pressed for work.

The a/c system also performs the function of clearing the windshield on very humid rainy days. I have a vivid memory of sitting in my un-air conditioned 72 Mustang on a sweltering summer day during a summer downpour; stuck in traffic, The windows were closed to stay dry, and I had to run the heater to clear the windshield. Fun times, let me tell you.

Excellent responses. Enjoyed reading every word!

Thanks for the responses. Agree that the weight doesn't matter for this car, especially if I need to buy a bracket to replace the compressor. I may change my mind if the box under the dash is moldy or not. I'll find out soon I guess.
