Question about 1999 GMC Sierra
I found the fuse blown so i change it and it worked for a while now the front wheels will not engage, fuse is still good so could it be my actuator. If any one can help solve my problem leave me an e-mail i would greatly appreciate it.
One simple thing you can do is to check for power at the actuator. With the truck NOT running, move the transfer case selector into 4wd then trun on the key to the hot posistion. Using a test light,check for power at the plug. The hot wire is the brown wire. If you do have power at the actuator, the the actuator itself is most likely bad. If you dont have power, then the switch in the transfer case is bad. Your best bet for a new switch is GM. The local parts places usually have no clue about what you'll want. If you have more questions......email me at firstname.lastname@example.org
