How do fix dashboard lighting only visible at night
I repalced the 6 with a 302 auto,the starter wanted to stay going even after the key was off.I replaced the lock cyl and ignition switch nothing changed so I replaced the solenoid tore the dash apart looked at all the wires and fuse panel nothing, replaced the starter even put an in line100amp kill switch between the solenoid and the only wire to the starter still does it.I tried both points on the noid also".HELP" out of ideas
I used to own an 83 T-bird and loved it...want another one someday .....would like to know all the options that were available. The 83 is the only one I know of that had the "smokers windows "...I really liked that cause I didn't have to run the air conditioner ...had Mustang GT wheels on it so it hugged the ground and ate up the curves ...
