Not getting any cool air. Topped off the freon, clutch won't kickin, jumped switch at accumulator and clutch kicks in. Still no cool air coming out. When running, low side is showing a negative reading, high side is about 90. Haynes manual indicates that may be an obstruction on the low side. So I don't get ripped off, how much should it cost me to get the system flushed and refilled?

 

Still may be too low on freon ,what was your static pressure reading? if below 80-90 ,may just need a orfice tube replaced.if your not familar with this system it could be difficult.

 

I added more freon (134a) until the clutch would run continously rather than cycling on and off. I may not have given it a full charge but I'm afraid of overcharging it also. My wife is happy as long as it cools in the heat we have been getting. Thanks for the help.

 

If it works for you it works for me!
