4WD button blinking but NO 4WD '99 Blazer
My 4WD has always woked and yesterday went to switch (on the dash) from 2WD to Auto 4WD or 4WD and it won't complete the transfer. The light will simply blink for about 30 sec and then go back to 2WD. Could this be a low transfer case oil level?
I did stop and switch to 2WD Lo and it switches the transmission but I'm not certain that it is in 4WD as the 2WD light also stays blinking. Things seem to click like they used to, but it doesn't complete the transfer by having a solid 4WD light. And I do not get 4WD to the wheels.
Any thoughts? I have a '99 Blazer ZR2
ADDED: I also note that my AC/heat is stuck in the vent mode...does this make a vaccume leak more likely? Where should I start to look?
