'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
What kind of problem(s) would produce this kind of symptom?
