A C question

[ivantruckman]

i have a 85 gl wagon ...i fixed a leaky hose, evacuated the system, and went to recharge the system, and compressor clutch would not cycle , is there a low pressure switch in this system ? if so how do i jump it out. were in the low 90 degrees and muggy. of course they never fail when its cool outside , any help would be appreciated.

Yes there is a low pressure switch. I am not sure where it is on your vehical, but it is sometimes on the receiver dryer. Just un-plug the plug and short it out with a paper clip or whatever is handy. Sometimes the plug is on the compressor. It will be in the line somewhere. (low side) Also when you start to charge the system set the controls in the car to hi cool and blower to high.When you start with the system vacumed it will suck almost a can in before you even start the engine. Have fun. Sorry I can't help more.

Been a long time but I remember the high side dropout is behind the passenger side headlight. The low side....I think was up higher nearer the firewall. After you get the first 12 oz or so in it should start cycling - do you have a scale?
