Question about 2004 Isuzu Rodeo
CHECK 4X4 LAMP IS ON. WILL NOT SHIFT INTO 4 WHEEL DRIVE. HOW DO YOU RESET LAMP? TRANSFER CASE WAS REMOVED AND REINSTALLED , ALL SHIFT SERVOS ARE CONNECTED.
sounds to me like the selanoid that locks in the front axels in is not working. might be a place to start. easy chk. unplug it and take it out put 12 volts to it and see if it moves. you can also chk. to see if you got power to that plug. test with testlight. hope this helps.

One thing to check, which is often the culprit in these situations is the U-joints. With the truck off, crawl under the vehicle and grab hold of the shaft leading into as well as the shaft going out of your transfer case, If htere is a lot of "slop in it, chance are it is in need of repair. Also I would check the oil level in the transfer case, in an attempt not to challenge you intelligence, there should be a plug located in the lower part about 2 inches from the bottom or so. it usually has a square hole that a 1/2" ratchet fits into. Pull the plug, and stick your pinky into the hole, you should be able to feel the lubricant just below the hole, if not it is in dire need of a filling. also check for metallic remnants in the fluid. this is a sign that things are not as they should be. In that case contact a repairman for a more thorough look.

Encoder motor located on the transfer case is usually the problem. It is the motor that shifts the transfer case.

Testimonial: "Will look into this and report .Thanks so much"
Hahahaha!... Seriously....!?!?! First off don't try to use a scan tool. The 4WD system isn't integrated into the OBD system. You won't get any codes related to 4WD.
Most likely the problem is defective shift solenoids. There are two shift solenoids which control the engagement and disengagement of the 4WD (locking the front axle gear into the the driveshaft input). These solenoids are located on the front axle. They have their own small skid plate. One is blue, and one is gray. One controls engagement, and one controls disengagement. One is a normally closed electrically controlled vacuum solenoid, and one is a normally open electrically controlled vacuum solenoid.
I'm not blindly recommending changing these, but usually one of these are the culprit of the problems you described. I'm even more confident in those being the problem due to your explanation of the the intermittent problems. At any rate test first.
The other components of the 4WD system are the vacuum lines and the actuator which is also located on the front axle and covered by the forementioned small skidplate. Moderate to serious rock-involved off-roading with a stock suspension usually results in this component being damaged.
