My rear lamps all work. Running lamps work, turn signals also work both left and right....HOWEVER, only the driver side brake lights work, Third light works.
Passenger side brake lamps do not work. Obviosuly not the bulbs or the fuse.
I can remember having this same issue about a year or so ago...it was suggested that the contacts might be dirty on the connector which is located on the rear passenger quarter panel towards the rear. I took a look at it, and it was pretty dirty on the outside. There are 4 sets of wires that attach to that connector. Does anyone one know which color connector is the one for the passenger side brake lamps???
Nice to see there are alot of new people on here......lots of new names. Where are all the old guys?????sk7 always seem to be fun of info...you still around?
Any help would be appreciated. Otherwise I risk getting a ticket :-(
Does anyone know much about the four sets of wires that go to the junction box for the rear lights?
I am assuming that one set is a feed....
One set maybe for trailer lights???
anyone know which of the four controls the brake lights for the passenger side??
Hey Oldworld! Sorry I missed ur post, thanks for the PM didnt know my inbox was full lol! I emailed u info on this issue, here's the wiring diagram and connector C4 info that supplies ground to both brake light sockets. Lmk how it turns out!
Connector Part Information
• 7-Way F Global Tech 280 Series (BLK)
Pin Wire Color Circuit No. Function
A LT BLU 1320 CHMSL Supply Voltage
B BRN/WHT 2609 Right Rear Park Lamps Supply Voltage
C BLK 1750 Ground
D BLK 1750 Ground
E LT GRN 24 Backup Lamp Supply Voltage
F DK BLU 2115 Right Turn Signal Lamps Supply Voltage
so did you figure out ur problem?? Im havin something similar on mine, my passenger brakelight light was burnt out i changed the bulb with a new one, it works fine along with the signal light, but now my Running lights dont work anymore but were working fine.
Well....thank you sooooo much for this great information.....as always!!!
I took all of the 4 connectors off (they were very dirty) I sprayed some electronic cleaner spray on all the terminals on the connector terminals and on the junction block.
Put them all together and everything worked fine.
Too bad GM never made a cover to better protect that connector plate.
This is the second time in two years I has a problem with that same plate.
Anyway...for now all is good.
ON TO THE NEXT PROBLEM lol
I agree the location for that junction box is not great! Right behind the rear tire, and no protection whatsoever! Had to pry off tar and 5yr old mud off of mine when I was hunting for the ALC-SCM problem.
can you or anyone repost the pics for the wires.. The large plug just past the junction box has a burned out pin I need to know which wire it is for.. I have no brake lights on passenger side and all the contacts are clean thank you in advance for all your help
