Having problems with your GMC Suburban ?

DRL works all the time...turn lamp switch on ..don't get brighter...and highbeams don't work.

Answers :

The DRL's are separate from the actual headlights. It sounds like your headlights aren't working at all. The first thing I would check would be the headlight fuse(s), or relay(s). The location for these should be in your owner's manual.

Hope this helps!
