Ok I just installed a 2 inch body lift. Well Im through, and everything works great. Except for this:

The passanger head light is very dim all of a sudden. When I turn the blinker on that side it just stays sometimes blinks once every ten seconds. The blinker part is dim too.

Whats wrong?

Check your motor to body ground. It's a braided cable that usually goes from the exhaust to the fire wall. doing the body lift may have caused this to break. I've seen really bazzar things occure when this ground breaks. A simple way to check is to take a resistance reading from the exhaust to an exposed metal body part. You should have good continunity reading, if not run a new cable.

check also all of your wirirng harnesses

ok well i hit a TINY bump and the head light got brighter... but when the lights are on, the blinker thing still happens. i will check it out tomorrow.
