My headlights were working on and off and I read that there was a recall on the LCM. I was holding in the turn signal lever and the lights would stay on, however the day before I brought the car in to change the LCM the lights did not work at all. I had the LCM changed and the lights still don't work.

Change the fuse and it works fine except the ABS and brake idiot lights are constantly on. When you turn engine off and turn the A/C back on it blows the fuse. Then the idiot lights go out, the defroster switch is out also. No codes show on computer..it comes up "no codes". Do I need a new compressor, is it drawing too much power causing the fuse to blow, or is the fuse blowing causing the compressor to shut down? Thanx everyone......
I am replacing the rear air spring in my 2004 Mercury grand marquis. I am having trouble reconnecting it to the solenoid. It won't engage to the final lock position. I have tried brute force and oiling the o rings but neither of these things have worked. What am I doing wrong.
