Question about 2000 GMC Envoy

1 Answer

The passenger lowbeam on my 1999 gmc envoy blew last week, but when I turn on the lowbeams, that light flickers. does this mean there's a short to that headlight and not that I have to spend $1300.00 + to get it fixed?

My headlight are not working but my parking lights and my fog lights are? What should I check/

Are your "brights" working. If so, change relay #46 with relay #45. If your lowbeams work again, get a new relay.

Lowbeam head lights dont't work after changing bulbs

{: ) For the lowbeam headlamps, check these fuses at the underhood fuseblock:
HDM 15amp (main power for the HDM relay. Important)
Voltage is always present at the HDM fuse. When you switch on lowbeams, voltage should be present on the LT and RT fuses. Otherwise check the HDM relay or swap it with another known good and similar relay.
Check the two fuses again for votage:
If voltage is now present, proceed with wiring checks, checking for open wiring going to the bulbs.
If voltage is still not present on the two left and right fuses, but the HDM fuse and relay voltages are okay, you may be having a bad fuseblock.
