Transmission problem
2001 Chevy Blazer V6 Four Wheel Drive Automatic 116000 miles
When I push the 4 HI button to engage 4 wheel drive the light just blinks. It doesn't make any sound it only blinks. What could be wrong?

There is a fault code stored in the transfer case control module. The 4wd will not work until the fault is repaired.
