Ok, I"ll try not to be long winded here.
Bought my CL about 1.5 months ago and AC worked fine, however, i was getting water in passenger side floorboard AND when i turned corners it sounded like a washing machine around the glove box. I also have pulled 2 leafs out of vents, so i know there was crap in cond/evap. I had a guy blow out the drain line and my passenger side doesn't fill up with water anymore.

One day the AC just up and quit. However, If i turn the fan to HIGH ie. 4 marks, then air actually starts blowing, but the compressor doesn't come on. AC doesn't work at all on fan speeds 1-3.
I took it to AC shop today, freon is ok(said it was low about 1 oz), he says its electrical. Checked fuses and relays and he said they were fine.

Anyone have any ideas?

Thanks in advance
Steven

 

When I first read your post I thought - "resistor pack". But the CL does not have a resistor pack. But...

From the Mitchell Manual... BTW. The figures suck... So I didnt include them. Power Transistor is behind glove box.

Blower Motor Runs On High Only
1) Disconnect power transistor 3-pin connector. Check for continuity between ground and Black wire. If continuity does not exist, check for open in Black wire between power transistor and ground. If wire is okay, check for poor ground connection.
2) If continuity exists, connect jumper wire between power transistor connector Black wire terminal and Blue/Red wire terminal. Turn ignition on. If blower motor does not run on high, repair open Blue/Red wire between power transistor and blower motor. If blower motor runs on high, turn ignition off and disconnect jumper wire.
3) Remove stereo unit and disconnect climate control unit 20-pin connector. Check for continuity in Orange/Black wire between climate control unit 20-pin connector and power transistor connector. See Fig. 2. If continuity does not exist, repair open Orange/Black wire between power transistor and climate control unit.
4) If continuity exists, check for continuity between ground and terminal No. 1 (Orange/Black wire) of climate control unit 20-pin connector. If continuity exists, repair shorted Orange/Black wire between climate control unit and power transistor.
5) If continuity does not exist, disconnect climate control unit 12-pin connector and turn ignition on. Check for voltage between ground and Blue/Red wire terminal of climate control unit 12-pin connector. If battery voltage does not exist, repair open Blue/Red wire between climate control unit and blower motor.
6) If battery voltage exists, turn ignition off. Reconnect climate control unit 12-pin and 20-pin connectors. Test power transistor. See POWER TRANSISTOR under TESTING. If power transistor is okay, check for loose wires or poor connections at climate control unit 12-pin and 20-pin connectors, and power transistor connector.
7) If connections are okay, substitute known-good climate control unit and recheck. If symptom does not exist with known-good climate control unit, replace original climate control unit.

POWER TRANSISTOR
CAUTION: Be careful not to damage locking tab when disconnecting and connecting wire terminal. Insulate Orange/Black wire terminal from body until testing is completed.
1) Remove Orange/Black wire terminal from power transistor 3-pin connector.
2) Connect 1.2-3.4 watt bulb as shown. See Fig. 10.
3) Reconnect 3-pin connector to power transistor. Turn ignition on. If blower motor runs, power transistor is okay. If blower motor does not run, replace power transistor.

 

JLatimer,

Sorry for delay, been outta town. Thanks kindly for the thorough suggestion. I'll take a stab at the walkthrough tomorrow.

also, i'll take a stab at downloading that manual .. seems like the information is great.

Thanks again for reply
