I just replied to an older thread, but thought I should start a new one coz my problem does not seem to match anything on here.
I've got an '05 Exp Sport Trac that I bought new (original owner). :yelexp: I don't normally use A/C, instead preferring to have the windows down. But my G/F likes A/C so I guess I like A/C too...
Anyway, I turned on the A/C for the first time this year and get very little cool air. First time I've ever had an issue with the A/C so I just assumed that I needed a recharge. I bought a recharge kit from AutoZone. When I plug in the pressure gauge to the Low Pressure Port, turn on A/C to max, and wait for pressure to stabilize - only it does not stabilize.
I hear the compressor kick on and pressure rises to 55psi. Then the compressor kicks off and pressure drops to about 15psi. Then the cycle repeats; compressor on for 10 seconds till it hits 55psi, then off 3-4 seconds till pressure drops to 15psi. And the blowing air is only mildly cooler than ambient. I'd post a video of the cycle if I could...
Any thoughts on what the problem is?? I'm fairly good with my hands mechanically speaking (I change my own brakes, water pumps, etc) - but I don't know much about A/C systems. The little I've read makes me think a clogged orifice could cause this problem??
