Transfer case not working

Since the key is stuckin the tumbler, now is the time to replace it. The top of the steering column has to come apart to do this. Beware of the air bag.

This could be a problem with the shifter not quite moving to right place when placed in park to cause the key locking solenoid to release the key.

There are several parts that could be causing that, disassembly to find the problem is probably req'd

Struggle as in crank for a long time or the engine cranks but real slow?

Have you checked for power to the 4wd actuator on the transfer case?

Those are all transmission codes, take it toa trans shop. Also check to make sure your battery is good as that may be the cause of your gauges not working.

It may be a bad connection at the trans or broken wire, this would need to be physically looked at for repair

Check and see if you have power to, and across IGN 0 fuse in the left fuse block. If you do, clear the codes and see if the condition still exists. If you do not, replace the ignition switch. It supplies power to IGN 0 fuse, and subsequently all the solenoids in the transmission.

THIS MAY BE YOUR TRANSFER CASE. EVEN IF IT AIN'T, LOOK FOR THE SAME KINDA POSSIBLE PROBLEMS THAT I SHOW IN MY PIC

THE MEDIC

POSSIBLE CAUSE:CORRECTION:
Blown A/C-HTR Fuse. Replace.
Faulty transfer sw. Replace.
Faulty 4WD Indicator light, sw, or wiring (4WD engaging but indicator light not coming on. Repair as needed.
Transfer case linkage improperly adjusted or disconnected. Adjust or repair.
Faulty transfer case: Drive chain broken, range selector ring brokenRepair
Faulty front axle
also if it goes in 2wd drive then that eliminates a transmission problem.

If you don't have electric switching you don't have the light. Or it in the dash.
