Question about 2002 GMC Envoy
The 2002 model year had problems with the TCCM (Transfer Case Control Module) going bad. Find one at a salvage yard, get one from a 2003+ vehicle.

Clicking sound- Possible electronic fan clutch failing. This is a typical problem with the 4.2L I6. When you hear the clicking, open the hood and listen if its coming from the fan clutch on front of the engine. this could also cause abnormal engine and transmission cooling. As for the "N" light and 4wd issue, have scanned at the dealer....Hopefully this helps

check the transfer case selector motor, they go bad and thats what happens, no 4wd and no other lights on switch because its not doing any changing of the tranfer case, to test remove motor ground it and with connector connected, try to switch to 4wd see if motor moves, you can use a test light to make sure its getting power, hope this helps.

About 45% of all transmission problems are due to a defective battery, its components and the charging system. Make sure you have the correct battery in the vehicle and inspect all items relating to the charging system and the battery. The vehicle should charge between 13,5 to 14.5 volts. The condition of the belts is part of this inspection. If all of this is A-ok then get a scanner and pull the codes in the PCM.
Remember once light is illuminated for a item that item no longer works. Once you've gotton to this point let me know and I'll walk you threw it. Hopefully its just a weak or incorrect battery or something along those lines. Good luck and keep me posted
