IF THIS IS THE FIRST TIME THIS LIGHT HAS EVER COME ON, AND YOU HAVENT BEEN PUTTING THE 4WD UNDER ANY STRESS, IT MAY JUST BE A LOW FLUID LVL IN THE TRANSNFER CASE. IF FLUID LVL IS FINE THEN THE SENSOR THAT SCREWS INTO THE TRANSFER CASE HAS TAKEN A DUMP, REPLACE, AND THE LIGHT SHOULD GO OUT AFTER THE ENGINE RUNS A CYCLE. MAKE SURE THAT THE 4WD ISNT PARTIALY ENGUAGED, PUT THE TRUCK IN 4WD AND DRIVE A FEW BLOCKS THEN STOP DISENGUAGE AND SEE IF THAT WORKS..

My chevy tahoe says service 4wd what do i do


Hi sspain.... Generally when this light appears, your transmission needs to have the fluid changed, the filter changed, and the belts tightened or adjusted. This work requires a lift and special tools. You can do it your self but even I take mine into the transmission shop for this. I like AAMCO repair shops for fair pricing, and quality work. Joe

Thanks for choosing Fixya!

My "service 4wd" came on and my push button 2wd,4wd, auto 4wd lights are off...is this expensive to fix?


You definitely need to have it serviced & checked out...The service 4WD indicator read across my screen, but I did not have serviced...Eventually, I heard a grinding noise & because I didn't have it serviced when I took it in, it was found that the transfer case had no tranfer case fluid at all...This damaged the transfer case which had to be replaced (used transfer case-$400.00)....The transfer case is part of your transmission...The shape mine was in could have broke my transmission...Have it taken care off before it gets too bad...You must use only GMC Transfer Case Fluid

4wd light says service


Does the 4-wheel drive work ? Most of the time, it is a reminder to have your fluid changed. Other times, it could be a vacuum leak in the line that engages the 4-wheel drive. Check both of those first.
