Similar problem with my 2002 Kia Sportage. Lever engages, dash light indicates 4WD but truck still in 2WD. Dealer checked out, told me "solenoid valve frozen" and needs replacement. .
Its a ford, found on road dead!
Check the fuses
i think these is not a proper question i do not know
check the fuses.
Make sure you lock the hubs if your vehicle has locking hubs. However, it sounds like a fuse, check your fuses. Kev.
Yes it depends what kind of vehicle you drive as to where the fuse is located.
I have found them myself ... my car is a right-hand drive car and the fuses are on the left-hand side, under the dashboard with a protective panel that opens down (protects the fuses from your feet etc)
First, the clutch won't engage if the refrigerant level is low. Start there. Next, check the sensor at the receiver/dryer.
check the thermostat that runs the fan.
This could be because you have a leak in you A/C system causing a loss of freon. When there is not enough freon in your system the A/C compressor will not engage, it will harm the compressor.
Depending on the year and make , the 4wd fuse is located were all your fuses are,
Its beside the fuses on the on the passenger side of a right hand drive car.
