Pwr seats, pwr locks, headlights not working
I have a Concorde 98. Last week my son decided to side swipe a tree.
I changed the front quarter panel and two days later the left side wheel came off.
Now the pwr seat, pwr locks and headlights don't work. The headlights can be put on highbeam, but you need to keep the highbeam lever pulled towards you the whole time.
From searching it looks like it it probably a BCM that needs to be replaced. I have seen some people recommend an ignition switch.
How do know when it is a BCM or switch?
Also the the HVAC Blower motor is on high all the time. It looks like this might be the resistor.
The local junk yard has a few LHS 300 cars. One is where I got the front quarter. I thought intrepids and concordes where interchangeable, but I guess they are not.
Is there site that can tell me which model years of Concordes, LHS, etc are compatible with what I have?
Thanks for any help.
