Well i found that my passenger side relay was messed up and was causing my headlight not to pop up. So today i went to Napa and got a new one. I get home and put the new one in and push the lights to go up, and HOORAY THEY GO UP! However i push to go down.... and only one goes down. The one i just tried to fix will now go up but not down. What is the problem?

 

Possible causes:
-Bad isolation relay
-Bad connection or ground
-Faulty actuator motor limit switch
-Bad actuator motor


This is how they operate:

------Blu---Grn---Gry
up: -------(+12v)------(-)

dn: (+12v)---(-)

I think +12 volts should be present at the wires when thay are powered, though I'm not sure.

Hope this helps some, let me know if you need more help.

yeah that doesnt really solve my problem yet. Like i said the one headlight will go up perfectly fine, but not down. i dont know why. When i push the button to go down the light goes off on this one but the headlight wont go down. anyone else know whats going on here?
