Service 4 wheel drive safe to drive 2 wheel

[thirsty1258]

Hello all I have a 2007 z71 suburban and this morning while backing out of the driveway to take my son to school the truck felt very sluggish. Bby the time I hit the street the service 4 wheel light came on and I parked it for a second and switched the truck from auto to 4 high the light turned on I tried 4 low and now light so I switched it to 2 wheel and I had a light.

I drove in 2 wheel and it didn't feel any different but I guess my 4 low is dead or something.

I have 95000 miles on it right now and do not know much about these trucks.

Is this something I need to get done ASAP or can I stay in 2 wheel. Also any idea of pricing to fix this. Funds are tight right now and hopefully things change in the next few months.

Thanks again

You should be fine in 2wd But I would get it looked at and stay out of Auto or any 4wheel drive selection in the meantime

Thanks I was assuming that while backing out of my slightly inclined driveway it must have auto engaged 4 low in reverse and it broke eventually.

I have my buddy that works for gm who can hopefully get parts if I need them.

Its probably thinking it has to be in 4wd or the actuator is bad. Get it checked out and fixed.

Same thing happened to my Yukon at 38K miles, it was a faulty actuator. Although covered under warranty the receipt showed $20 in parts...throw in labor and you're still under $100. took about 45mins to fix.

My 07 did the exact same thing on one of our colder days here in texas about a week ago (it was around 29* leaving for work in the morning)
same deal: backing out of drive way, then sluggish low power feel, service 4wd light came on (i was in auto), switched to 2wd, parked and shut her down
about 30 minutes later after cosulting my manual and the internet, i fired it back up (no service 4wd light) drove around for a few min's in 2wd w/ no issue, put it back in auto and cruised around w/ no issues and hasn't happened again since.

Could cold weather have anything to do with it?

Also, does anyone know if the warning light being on mean the 4 Wheel Drive isn't active?
