Today it was in the 70's in NC. Before I put the top down I was running the air conditioning (AC) in stop and go traffic. I noticed that the AC compressor seems to cycle on and off. When on and during slow acceleration from a stop, the fan (I think) makes a noise. I confirmed that the AC system is the problem by pushing the AC button and the noise stopped.

Anyone out there with this problem and possibly a solution? The noise is getting worse and it is aggravting. I hate the idea of the dealer taking my dash apart even if they know what they are doing.

I have been told by my SSR buddies at GM that they don't have anything wrong with them. You must be having one of those unlucky days in your life and bought the only defective SSR. Just kidding, but mine seems to stop cooling for no reason and it even did the same thing for the dealer. No solution to my problems and I don't look forward to it being fixed in the near future. our dealers mechanics hate SSR's

If your blower motor was on setting "2" and you heard a "knock-knock-knock" noise coming from the blower motor, then yes this is a "known" issue. My SSR had this issue. There's a TSB out on the issue:

"Advance Service Info - Blower Motor Noise on Second Speed Setting (Fix Not Yet Available) #04-01-38-004 - (Mar 4, 2004).

2003 - 2004 Chevrolet SSR"

My service department replaced the blower motor stating "problem fixed". When I drove off of the lot and turned on the blower motor - guess what - it wasn't fixed. That's when I looked on the NHTSA website and found a TSB on this issue and the document reference I noted above was "found" by the service department after my report to them that a TSB exists.

I don't know if it's been fixed yet since I no longer have that SSR.

Shiftz33,

thanks for the reply. Sounds like the same problem as it occurs on the second blower setting. I hate to do it but I'll check the TSB's and discuss with the dealer.

If your ac is cycling ie the system was on the full ac mode and your pump was going on and off it could be 1 of many problems
1 not enough r134a refridgerant and the presures are too low in the system and the presure switch is turning the system offand on as the safety switch decides
2 the system is building up too much presure and the system safety switch is reading too hi and is shuting the system down
3 defective hi lo presure switch in ac system under hood
4 you had the system on defrost , the defrost cycle of your heater system cycles your ac system on and offf even when the system is on heat and the ac is off , you will hear the pump click on , and turn off in about 5 seconds . this is normal,. but check ac controls in your manual before youtake it to the dealer
this is just afew of many problems , coud be in the dash also
