Serv 4wd lite on but no lites on 4wd selector
Check Fluid in Front diferental. It has a sensor that when fluid levels get low it will flash a light. If it is low I would recommend adding Lucas Diferental additive and finish filling with dex-merc trans fluid
How do you replace front crank seal on 02 avalanche
The front crank seal is behind the oil pump on the LS series motors. There is also a seal at the crankshaft and harmonic balancer on the front timing cover. This is typical leak area. You can carefully remove the harmonic balancer with a puller, replace the timing cover seal and reinstall. Make sure not to pinch the seal lip You will have to have a special tool in order to re-install the balancer, which is extra long to squeeze it on the tapered shaft. I do not think the other crank seal is an issue since it drains to the pan behind the oil pump.
How do I get a brake light sensor back the brake pedal of a 2002 avalanche
Get a replacement from a Chevy dealer and it should be obvious as to how it is installed.
First check to see that the one you have is just not out of adjustment. It should screw into a bracket with a locknut. Also check that the bumper on the pedal that presses on the switch is OK.
Lay on your back on the floorboard of the truck with a flashlight. Wear safety goggles so nothing falls in your eyes.
Why do I still have a Rough Idle and P0300
I have encountered this before and it was the vacuum supply line from intake to the fuel pressure regulator sucking fuel through regulator. it could also be more serious like intake gaskets

if you read the owners manual it should give specific instructions on resetting it, if not, then call your local Chevrolet dealership, and ask for the service department, and they should be able to tell you exactly what to do.
My break not working very well
the problem is the front abs sensors,the front rotors need to be removed first,then the sensors need to come out of the front hubs,the sensors are held in by an allen head bolt,there is a 50% chance the sensors will break upon removal,after you get the sensors out,you need to clean the rust on the mounting surface where they sit on the bearing,after that just reinstallthe sensors andtake it for a ride
