I've been turning a wrench on my own cars/trucks for 50+ years but this has me totally scratching my head.
2005 Express 2500 extended wheelbase, 4.8L, 4 speed automatic. Basic utility setup.
Randomly.. the "anti-lock" light will come on. When this happens the A/C/heater blower motor shuts off. I can see no relation of heater/A/C and anti-lock brake sensor. It will last up to 10 min. or so and then back to normal operation.
Anybody ever hear of something like this?? Makes me nuts when it's 90+ degrees out. Any ideas as to where to start looking for solution?
Thanks!
