My truck is having an intermittent problem that's more annoying than anything right now. The truck is a 2003 Silverado 4x4 and every once in a while upon start up, the selector switch for the 4 wheel drive will not light up and the truck feels like it's in 4 low. When it happens, the selector switch does not work so I have to turn the key off and let the truck sit for a few minutes and when I restart it, it is usually back to normal.
Since it's an intermittent thing without a code the guys at Chevy say it could be either the switch itself or probably the actuator. I'd rather not just change parts and hope it's fixed so is there a way to test the actuator to make sure?
They also suggested I keep driving it when it happens for the error code to pop up. Not sure I want to do that just in case it could break something while it's in 4 low on dry streets.
