CHEVY 4WD NOT ENGAGING

Transmission problem
2000 Chevy Blazer 4 cyl Four Wheel Drive Automatic 81500 miles

If my alternator is not working properly; will this cause the 4wd to not function?
Thank you!

Hi: If you have electric shift 4wd and the battery is nearly dead, it may not engage. However, if the battery is strong enough to start the car, the 4wd should work. The actuator for the 4wd is on the transfer case. Se if it getting power when you shift to 4wd. If you are, the actuator is bad.

Let me know if this helps.
