The check engine light came on this past weekend for my 97 Concorde LXi with 3.5L V6.
I just had the oxygen sensor replaced last month when the check engine light came on.
The light dildn't not come on last evening or this morning when I took the car in to check this out. The service department said it would not be worthwile to check out since the light was not currently on. I really didn't want to spend the money since I was just laid off two days ago.
There is a problem though that occurred at the same time the check engine light came on. The automatic climate control is not working properly (blowing cold air when the interior of the car is cold etc.) The trouble codes pulled by a friend who used to work for a mechanic were "12" and "43". The dealer said these were "generic codes" and of no help.
Any input would be of help. I really am not in a position to spend money for repairs but I WOULD like to have heat in the car.
Thanks for any input.
