AC Compressor Noise

Hi all,

Just a quick question/survey for all 2001/2002 owners. Can you hear your AC compressor kick in when you turn the AC on? On all my previous cars(not Caddy) I always could. But on my previous 02 Base Deville, it was inaudible even when the AC was maxed out and I had my head under the hood listening. I know it was working as cold air was blowing in the car. My present '01 DTS is the same way. Because I bought it in the winter I was unsure about the AC working due to the quiet compressor. It is still cool up here in Canada, but I am concerned that I will get stuck without AC this summer and wanted to get a head start on any repairs that may be needed. Is there any sort of visual check I can make on the unit to ensure it is working?

Thanks in advance.

Thanks for the is still about 31 degrees up here( If I did the conversion right), and by the time it warms up, I am on the road for work. If/when we get a warmer day up here I will get someone to sit in the car and press buttons for me. I will let you know how it turns out.
I found the compressor and it is starting up no problem...but it still seemed to be blowing warm air. Then today I started the ac and was feeling the vents and happened to have my hand go past the passenger side vent which was blowing cold. I know I saw a post somewhere around here about that exact I am going to search for it and hopefully have a much cooler ride this summer.
Thanks Ranger,

I was just reading that in one of your earlier posts about the same problem. Guess I will have it topped up this weekend if I can find the time.


I was going to get the refrigerant topped up, but on a whim I decided to pull the codes.....and got B0429. Would this code go away after the refrigerant is topped off or am I looking at a more expensive repair?
