Chrysler Forum - Chrysler Enthusiast Forums - Air Conditioner not blowing

Hi guys,

I know this isn't the right forum but you all have been so helpful on my 2002 Sebring issues. This is regarding my 1997 Grand Cherokee A/C. Hey, at least it's a Chrysler!

Well here's the issue I had today. Have had a tiny leak somewhere in the A/C system for several years. Every early summer I add one can of 134a freon to the system and that does the job until next year. Today I hooked up the can and gauge and as usual, it was down to about 20 psi (with engine running) before charging. I started the Jeep, turned the A/C and fan to high and proceeded to charge the system. It took the freon about 5 minutes to empty and the pressure on the low side went up to about 50 psi which is normal. I did notice that during the process the compressor would go on and off every 10 seconds or so and I don't recall if this has happened in the past. So I complete the charging and unhook the can/gauge. I go into the jeep and lo and behold the fan is not blowing air and there is no hint of cold air coming from the vents. Puzzled as heck! Ten minutes earlier the fan was blowing like crazy.

Any suggestions on what just occurred would be greatly appreciated. Many thanks.
