2000 Cadillac El Dorado iinformation system

Sounds like one of the door switch's are stuck. Do the interior lights stay on as well?

to 2carprojack

Interior light goes out as it should.
Owners manual tell me that signal refers to
passenger door only. used wd40 on latch
mechanism. There are no other door switches.
Is my previous donation stlill in effect, or
should I resubmit a donation. I am willing
to increase donation to $15.00 for an
answer.
Thanks, Fred Greco

we are still working off the original donation.....You are correct, the switch is in thelatch mechanism, sowetimes WD will free it up. Otherwise you will have to remove the door panel to access the switch
