Dodge, Caravan, 1994, 75,000, 3.3L

Engine light comes on intermittently
when A/C is on. Restarting engine clears engine light for various lengths of time.

A/C works great.

Dumped a Code 33.

Cleaned relay and fuse terminals (appear to be aluminum rather copper).

Problem persists.

Searched TSB's titles this vehicle, but no specific mention this problem in title.

-------------------------------------------------

Other than new relay (which I have doubts this is problem) any help appreciated.

Thanks
David

=============================
RESOLUTION:
Pulled All relays in power center. Cleaned terminals and reinstalled. Appears to have resolved problem.
