I bought my truck (99 4.0) last summer and the ac wasn't working. I wasn't too concerned until this summer and I am sick of driving to and from work in a puddle of sweat. I added r134a-about 12 ounces- along with some pag 46, 3 oz. the compressor is kicking on, but immediately kicks back off, and repeats this cycle. It only stays on a couple seconds and is off maybe 10 seconds. I have one of those auto store refill kits with the gauge built in. The gauge shows pressure building until the compressor kicks off and then it drops again.
Should I keep adding r134 or is something broken? I would lean towards a pressure switch if the system is full. How do you check them?
