Question about 1993 GMC Sierra K1500
I own a 2001 GMC Sierra 1500 Z71. I have it on auto and last night i was driving in the snow and the service 4wd light first came on. I tried switching it on manually and it does not seem to be engaging. Any type of help would be appreciated.
Transfer case engages/disengages via a vacuum line. If the vacuum line is cracked, often by age and cold weather, it has to be replaced to allow a good vacuum pressure.
