Question about 1991 Chevrolet S-10 Blazer
When I try to ingage into 4hi it wont ingage. The light doesn't even come on. I use it last week with no problems. I am wondering if it might be as simple as a fuse? There is no type of noise coming from my transfer case or any thing of the sort. I looked to see if I might have lost a front drive shaft, and it is there. Please help???
The 4x4 uses vacuum to lock everything up (as does the heater to switch from defrost to floor to panel...) If you had said, "no, the heat works great" I would have suggested that you have the selector switch (on the T-case) looked at. But since the switch from defrost to heater took so long, I think you may have a vacuum leak... I hope this helps!
