Probably the shift motor
could be vacuum problem. have 2001 blazer 4 wheel would not engage lights blinked. vacuum hose was off by firewall
Had same problem with mine. I changed the actuator and it worked great
change engine oil and this should help
It's most likely the vacuum diaphragm under the battery. They tend to get corroded and get rotted. You can get all the parts thru Amazon.
I’ve got a “97” Tahoe ,and it did the same thing . In the end all it needed was a new switch. (The switch on the dash) I got one at the Dealer cost $60 for part.
