Pontiac Problems? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
Here is your wire diagram. https://dl.dropboxusercontent.com/u/90220402/Vibe1.pdf
Remove ground 103 at the left front strut tower and sand it. Swap the dimmer relay. Remove the headlight bulbs and confirm neither has damaged filament allowing the low and high beam filament to touch each other. Let me know these results.
Thanks for using Just Answer, and rating me so I am compensated, Chris
You can drill out the broken bolt, sand the surface and wire end and install a new bolt to repair this ground and retest.
The high beam indicator is saying on because it is getting a ground from the dimmer relay. The dimmer relay is what provides the ground to the high beams.
The DRL module controls the signal to the dimmer relay. The relay can either be on or off, not partially. We need to see why there is a ground all the time on the high beam circuit and why its not a good enough ground to fully illuminate the bulbs.
With the dimmer relay removed, is the high beam indicator still staying on?
Earlier you said "With the dimmer switched removed" which is why I asked about the relay again.
Can you do these tests https://dl.dropboxusercontent.com/u/90220402/continuity.png
Install the relay and try again. You should get the same result since the relay is not being commanded on.
With ground 103 not connected the left fog light should not work.
Does the WH/BK wire have continuity to ground? It should not. If so then there is something wrong with the wiring or fuse box, grounding this wire.
The vehicle did not come from the factory with a remote start. That was either added at the dealer or another shop. It could be a OEM add on accessory or aftermarket.
The DRL module is not connected to any of the wires we have tested. You can unplug the DRL module if you want. If all prior testing has been done right, this should still result in the high beam indicator staying on.
The module is above the brake pedal.
If the module is not to blame then you need to check all the wiring we have been checking to see if its damaged or altered.
Nothing must be removed to get to the module.
Hello again Chris here,
