Hi everyone. It has been a while since I have been on here. I have a couple of issues that hopefully you can help with. I dont see many A/C questions on here, maybe you are didicated to engine mechanical. My 2001 3. 4 Monte Carlo has 148,000 and I have kept up with the maintenance over the years so it is not in bad shape. I recently purchased a new HHR Panel so the Monte Carlo does not get driven as much. I still drive it once a week or so but when I drove it the other day the A/C did not work in it. It was working fine the last time I drove it. The fan still works on all speeds as well as the defrost settings, floor, vents, etc. I have also checked the compressor and the clutch still engages and still kicks on when turned on and does not short cycle like it would if it were low on R-134. Also I am losing a little bit of coolant somewhere. Not real bad but I cant find the leak. No drips on the ground or around the engine that I can find. I have let the car idle to heat up and turned it off to check all of the hose connections to no avail. I have replaced most of the heater hoses as well. I replaced the radiator about a year and a half ago and the water pump about 7 months ago. I can smell the coolant sometimes from outside the car and seem to smell it more in the car. I thought maybe the heater core was leaking but I cant find any evidence of coolant inside the car. Any help with either of thes issuess is greatly appreciated.
