Why don't my front tires turn qhen in 4wheel drive

Clicking is a problem. Do you use 4WD often? My rule of thumb is every month put in 4WD and drive for 10-20 miles. Keeps pumps working and lubes internal parts. Sorry, but have always had problems with GM 4WD. Try this in neutral or park turn switch to 4 wheel, wait for the light tho go off or noise to stop. Do the same in AWD then back to 2. Drive a mile or so in 2, then in all other functions. Oh yea also drive in reverse in all modes as well

My 2002 GMC envoy has a clicking noise in the dash and my service engine soon light has come on

Mine is doing the same thing right now. My husband says it could be related to the odometer, but mine seems to stop when I turn on the heater. I would be curious to hear something about this as well from someone that is mechanically inclined : )

I have just had to replace the transmission in my 2002 Envoy and once the change was made the check 4 wheel drive light (wrench with 4 wheels)is on the dash and wont go away. My mechanic had to disengage...

Apparently during the transmission service work something was disturbed, such as a connector. The mechanic should recheck his work and scan the system for fault codes.

Wont shift back from 4x4 low, to 2x2

I also have a 2002 Envoy. Shifting to and from 4wh and 4wa can be done on the fly but shifting to 4wL has to be done stoped and while in neutral. Try that. Otherwise I'm afraid its a new computer for you. Its located under the left rear seat and you need a loan for one.

Transmission problem with reverse

the reverse clutch has failed in the transmission, this will require the trans be torn down for repair.

Does not transfer from 2 wheel drive to 4 wheel drive

the next time you shift into 4 wheel drive, try backing up alittle bit and see if it shifts in and light comes on. i have a 1995 half ton chevy pickup and thats what i have to do do to get it to lock in.
