I have a 2002 OBS and when I went to use the a/c last summer it only worked for first 5 minutes or so - took it to dealer and they charged but then told me the compressor was shot and I was looking at $1,000. So I decided it was time to start doing more or at least learning more. Got some good jack stands - changed my oil etc but since I am headed to Florida for the summer I need to figure this out. Can't pay that kind of money.
Watched some videos and realized the first thing I need to do is buy a manifold gauge set. Should arrive this week. The system has a charge and the compressor clutch is engaged or at least spinning. But like I said it blows cold for the first few minutes only. It isn't real hot here yet on Long Island. When I turn on the a/c the vent thermometer takes it from 80 to 60 but then it fades back to 70 pretty quick. The high pressure line out of the compressor going into the condenser gets hot like I assume it should - at first - but after about 5 minutes it is just warm. The low pressure line going into the firewall is fairly cool but actually feels colder coming out???? Bad Evaporator?
Then when I went under the car it appears like the boot on my axle arm is torn under the driver side and sprayed grease everywhere....beautiful. Don't know how much that will cost.
And to top it off - when I was putting the guard back on top of my drive belts... the back plate(?) that takes the bolt that keeps my guard tight dropped into the engine area and can't find it. Black hole I guess.
Great day - all in all.
