Question about Chevrolet Suburban 1500

1 Answer

My 2003 Suburban is stuck in 4 wheel low

My 2003 Suburban switched to 4 wheel low when I started the car this morning (on it's own). It will not allow me to manually switch it to anything else. Any suggestions? Commuting to work in 4 wheel low is pretty much impossible.

It sounds as if it is a module eprom issue. When the key was turned on the program was scrambled.Try disconnecting the negative and positive battery cables. Once both are disconnected from the battery, touch the two cables together for 1 minute, this will drain the reserve energy in the module. This process will reset the modules to factory default.
Reconnect the battery, positive first then the negative.

The 4 wheel low light is on but its not in 4 wheel drive but the trans will not change to overdrive

Are you sure it's not in 4 wheel or do you mean that it's just not switched to 4 wheel? Sounds like a bad indicator switch in the transfer case which is indicating 4 wheel low to the ecu which might not allow overdrive due to speed constraints of the 4 wheel low system.

Stuck in 4 LO

Check your transmission fluid level. More than likely it's either low, but since you didn't switch it to 4 low, it's probably a vacuum leak. Remember it should be in neutral to switch back to 2 wheel drive.

1997 Suburban-4 wheel drive problem-Won't work-Indicator flashing

It sounds like the spring loaded pin that the plunger activates is stuck or broken. If its not to cold tap on the housing and see if it kicks in. If not consult the book for an exploded view. If your manual does not have the view go to the nearest dealers parts department and ask them to print you one.
