Re: Retractable headlight problem.
I can't be sure from your post but if this problem is with both lamps
try what NSX Pilot suggested. With the headlamp switch in the off position pull the stalk to the left of the steering column, the one you use to activate the high beams, and see if they go up for a moment.
If that works and not the headlamp switch you probably have a bad headlamp switch.
If it doesn't work check the fuses. If they're ok swap out the retractor relay with a known good one and try that.
It would be a good idea to look in the service manual for a flow sheet and test procedure.
It's not very likely both retractor motors went bad at the same time and unless you've modded your car such that it meant moving or splicing the headlamp wire harness that probably isn't the problem either.
Look for bad fuse, switch or relay.
If it is just one lamp try Engle07's suggestion and listen to hear if the motor is cycling. If it is, it could be one of the pivot arms on the retractor assembly is the culprit. If not, you have to check power to the motor(plugged in?) or a bad fuse, bad relay or pinched harness.
Good Luck.
