'94 Caravan with 3.0 liter engine.
Air conditioner stopped working last summer; do not want to go through another summer without it.
Started to investigate and noticed that turning air conditioner on did not trigger the solenoid that engages the compressor. Decided to by-pass normal controls and wired solenoid directly to battery to determine if it was a bad console switch or solenoid. Solenoid worked just fine. Reconnected to main wireharness and noticed console switch started working again. (Bad contact at harness?) However, compressor engages only for a few seconds and then disengages for a few seconds. This engage - disengage cycle repeats continuously.
What kind of problem(s) would produce this kind of symptom?
