My A/C
My A/C is not getting cold. I thought it was low on R134 but it'* full. When you turn it on you here it click on then click off. When I had the hose hooked up to fill it up, when it clicked the gauge would go up, then a second later it clicked off and the gauge would go down again. It keeps repeating this proces. Thanks for any help.

How long between clicks?
3 seconds or 15-20 seconds.
3 seconds would mean your low on freon. 15-20+ is healthy.
Does that gauge read full with the A/C on, or is that with it off?
It should click(compressor stops), gauge slowly rises to warning, click (compressor spinning) gauge moves into good, click (compressor stops), gauge slowly rises to warning, etc.
Post exacly what the gause does with te A/C on, and the time it takes to do it.

I'm going to start a new thread. AC is beginning to get out of control.
You can not rely on the coloration or general indication of correct pressure on a gauge that was not made specifically for your car.
Also..do not rely on another year FSM for the correct pressure as the correct pressure could have changed from year to year.
You need to find out the correct pressure from the correct year FSM.
Per my 97 FSM...my car'* correct pressure was not anything like that stupid generic gauge said it should be.
Follow the gauge if you want... my gut tells me you may be low, but I'm not there with an FSM and an gauge. If you get the proper information, that system will be running like a champ in little time.

Agreed Bill.... And even then you have to take into account the Type of compressor on you car.... For 94 it had the H6 compressor.....
Later years such as the 97'* had a V5 which is a variable compressor that does not need to cycle as the older H6'* did
Also keep in mind that R134a operates at diffrent pressures than does R12.... Myself and Bill were having that discussion about my 91 as I switched to R134a 6 years ago...
You really need a service manual and a set of gages to do it right
