LCM replacement

[ssmoke14]

Would an LCM from an 03-04 CV or MGM work in a MM?

Yes several members around here have used them :up:

Make sure you stay within 03-04 as the pinouts were changed slightly for 2005+ models.


Whether from a CV, GMQ or MM they will all suffer the same fate - eventual failure of the headlamp relay (especially 03 models)

If your replacement LCM works fine DO A HEADLAMP WIRING RELAY UPGRADE IMMEDIATELY!!! (If you don't want to make it yourself suvlights.com sells a 9007 kit that's plug and play)
That will keep the load off the LCM's relay (..and hopefully keeping it from failing any time soon!)
