Have you checked the front axle Actuator solenoid?

changed it

wqrked first snow not after worked well for 8 years


When the encoder shifts into 4wd it applies vacuum to the front actuator under the battery tray. Check for vacuum there. If there is vacuum there check the actuator for cracks because all it is is a vacuum diaphram. If it holds vacuum then see if the cable from the actuator to the front axle moves freely, they can seize. You should find your problem in here sonewhere.

All of that has been replaced.



Check things, is bacuum where it should be?

yes the vacuum is all right and mechanic has been checking all different things


If EVERYTHING is ok then its the TCCM.
