Hi gents,
Need some help. I changed left turn signal bulb from the top with headlights open. After changing the bulbs I wanted to close the lights the headlights motor would not response, also lost the back running light and lost the dash lights!!!??? Any suggestions? Question #2 If the zener diode by the a/c compressor go bad will it prevent the compressor to turn on(changed the hole a/c system a year ago with a rebuit compressor)cause now it does not turn on and summer is on its way. Thanks in advance for the help.

 

Did you check all fuses? This is what I would suspect.
