So a friend of my daughters has an 06 PT, all the lighting execpt the passenger side low beam functions brilliantly (pun intneded). Both head lamp fuses were fine (didn't know which one was left/right), but, no power gets to the bulb.
Bulb is fine, kid switched it to driver side, lights up. Signals are fine, high beams work, etc....
Local brake max says kid needs a new "power module" to the tune of $672.
It does not seem to me that a module (as opposed to relays?) would go bad affecting just the low beam circuit, but, I know nothing about these things, so please school me.
I must have issues posting on Christmas Eve, but...
Thanks, and Merry Christmas!
First thing I'd check would be the wiring. It's eerily similar to a problem I had with a '57 Chevy that had had an engine fire and baked the wiring. The front clip wiring was all brittle; it'd break if you looked at it cross-eyed. Locallized fire, maybe?
Are you sure there is no power? How about a bad ground? Did you get out the multimeter and tested at the plug or is this based only on the bulb swap "test". Not trying to be a wise guy just trying to save you / her a pile of $$$$.
Is there a way to test the PCM other than just swapping it. I really hate those places that will not test anything BUT if you plug the new component into your car it becomes non returnable. For something like this it may be worth paying some one to test the unit if it is not a DIY job.

There is a big multi switch that does most of that - easy to change.

Yeah, stuck a multi meter in the plug for the bulb, no juice - possible that I didn't get a good connection, but worth a retry.

Where is that bad boy located?

Junkyard, FTW
If it comes to that (sounds like it will?), that would be the next step....
Thanks to all for the replys, sorry to take so long posting back (and hope you all had a good christmas...).
The good news is (not), just had to replace the alternator in the e30; rear shock mounts next, so it seems as though this is the week for repairs....

Under the steering column. Called the "multifunction switch" or some nonsense. Mine failed and caused the fog lights to stay on. 15 minutes and $75. I have no proof that that is it, but it sounds right to me.
Are they HID headlights? If so, it's not uncommon for the igniter or control unit (box inder the headlight) to go out. Many people think HID's are just pretty headlight bulbs when there more like a compact flourescent than any filament type bulb.
