I had my A/C converted to R134 late last year (8/16/03) by a local shop. Everything that should be replaced was (accumulator and orifice tube). My a/c still is blowing fine today, but the compressor is cycling quite frequently and I was wondering if this is normal. When the car is sitting, idling, I don't hear the compressor click on and off. When I'm driving along, I will hear and feel (loss of power) as the compressor clicks off and on. I will hear a double click, and after 3 seconds I will hear the double click again with the same loss of over all power. I have the John Harvey fan fix and I know as the compressor is clicking on and off, my fan is as well (fan fail light illuminates). As this is happening, while driving at night, my headlights tend to show the loss in power as well. I'm assuming because of the fans and compressor are clicking on all at once. Should the fan be on at all times with the a/c on, or just when the compressor is on? What should be the average cycle time from when the compressor clicks on and off (like on a hot muggy day)? What should be the high and low pressure on the A/C? Thanks everyone.
