Default Re: Testing AC clutch with intake on???

My 92 has had AC issues for the last few years. Works fine, then hit a pothole and it is out. Checked all connections, all were good. Turns out the AC controller which is under the drivers side dash above the gas pedal had some issues with the circuit board. Got the AC controller out and sent to Batee for a rebuild, got it back 3 days later. Installed the new controller and nothing, including no fan. Fan motor fried. Put in new fan motor and blows great but no AC clutch engagement. The tech hooked up the high and low pressure gauges and the low side was reading very high???? He took all the freon out and it was 2oz more than what it should have been. My system held pressure for 30 minutes so no leaks. He put back the correct amount and now everything works great! I had no idea that a little extra freon would shut everything down.
