    Depending on what year you have, this might help.

    1988 and older (maybe newer but them I don't know about) have a receiver/dryer in the system mounted on the right end of the radiator. On top of it is a 2-wire harness connection. That is the low-pressure kick-out switch.

    If you lift the connector just a little while leaving the contacts still connected, you can jump the contacts with a paper clip or some such. Do this with the engine running and the controls set so the a/c should be engaged. If you can hear and see the compressor engage, the test is over. Disconnect the jumper - the Freon is too low.

    A shop can run a leak test, and would LOVE to sell you the R-12 needed to fill the system at $60+ a pound. Get the test only unless that amount is OK in your budget. Note that the Volvo kit for R-134 conversion runs around $200.

    Good Luck,

    Bob

    If the fuse is good, it could be that you are out of Freon and the safety switch is preventing the compressor from kicking in and damaging itself.

      Thank you v70 dude. I knew nothing of such a switch. I guess I'll have to have it serviced & checked for leaks.

        Hey, I just recharged my '89 244 where the dryer is front mounted and i did the jump test before looking on here. i already have put in oil and stop leak and plently of R-12a in(the required amount+). Any ideas? the condenser runs when jumped and while running puts out about 37PSI which is like 47degrees. So far i have put in about 5 cans of R-12a in just to get it up that high, according to the instructions it says it only needs about 2-3, but i cant get the compressor to stay on. Do you know what PSI the switch kicks on so i can figure out if my switch is bad? Also, when the compressor is running i see NOTHING in the little spot glass thing. Thank you!
