air conditioning not cold
I have verified it is pressurized.
FWIW, I do not think the air compressor even 'clicks' on...there is no change in the idle speed and no noise like I'd expect.
Do these have any common problems with the air?

I do believe there is a common problem. Mine has not worked for over a year. People I bought it from siad they think it is the compressor. I have never had it checked, but i see them for sale all the time on eBay, so I figure it is common. Air is one luxury that I can't afford to worry about right now.

Like Mark said, it'* important to know what year and trim level, as the type of compressor you have wil make a difference. Plus the amount of refrigerant pressure you need varies by year, etc.
When you say the your system is pressurized, what do you mean? Have you verified that the amount of refrigerant is correct according to your manual?

OK, I believe you and don't want to harp on it, but since I can't tell by hwat you wrote, I'm asking the basic questions. What did you use to verify that your system had a charge already? The reason I ask is that some of the Bonnevilles take a much larger charge than most people think is "normal".
Did you use a set of A/C guages or just one of the recharge bottles with the cheap charge guage on it?

I used a guage I have. It is not super deluxe, but it is probably not a piece of crap either.
As I said...I dont hear the compressor turn on or the rpms change at all, like I'd expect.

See, that'* why I keep asking.
As I've mentioned above, most Bonneville years' A/C systems take quite a bit larger charge than is usually considered Normal. As an example only, my '97 manual says that pressures below 50 psi will keep the compressor from cycling. This is considerably higher than the "normal" 25-35 many cars use.
You will need to get input from someone with a '92 FSM or see if your owner'* manual or A/C sticker has the charge value on/in it.
However, if your charge is correct, do a visual inspection of the A/C wiring harness and check for loose/disconnected wires or connectors, check for A/C clutch rotation, and make sure your A/C fuse is not blown.
Those are the basics. We can go from there after you try those and if you don't find anything.
