I'm new to the site here and need some info. I have a 99 bravada (140K miles) and have recently noticed the Service AWD light coming on when I start up the vehicle. There is also a series of 4-5 clicks (sounds like a relay) coming from the glove box or passenger floor area only upon startup and only when the AWD light comes on. The light will stay on until I shut off the vehicle. Other times, the AWD light and clicking sound will not occur (they seem to work together). The AWD system seems to be working fine though.
I've seen some posts on here about the AWD light and the clicking sound, but not together in the same thread. But maybe I haven't found it yet. If anyone knows about this or has had the same problem and found the culprit, please post back. Thanks in advance for your help.
