4 wheel drive

Hi, i have a 2002 jeep grand cherokee, we just got some snow, i shifted into 4 wheel hi and nothing happened, no light on dash. I have tried the part time, 4 wheel low and it does not engage. What can i look for next? Thanks.

Did you shift "at speed" or standing still? At speed is what you want to do.

Do it while rolling a little 4H will or should go in at any speed below 55 mph.

Actually at "any legal speed"


Here's how the factory suggests you shift the transfer case and I've been doing this since these things were new and I worked at the dealership. Quoted from the owner's manual.

"To engage, shift the transfer case lever from 2H to 4H while the vehicle is moving at any legal speed". I let off the gas, throw the lever, and then tap the gas and let off.

4L position: " To engage, slow the vehicle to 2-3 MPH , shift the transmission to Neutral, then shift the transfer lever to the right and pull firmly rearward to 4L".
