2005 Dodge Ram V8 Four Wheel Drive Automatic 94000 miles
The 2 wheel drive in my Ram works fine & shifts fine between gears. When I use the floor shift to put it into 4 wheel drive, nothing happens. No light on dash to tell me it's in 4 wheel drive. No noises what so ever. Any simple solutions that my mechanic can check or do I need to take it to a Transmission Shop?
First, make sure the linkage is attached and working. Next, there is a vacuum switch on the front of the transfercase with 4 vacuum hoses going to it. Check if any of them are damaged or disconnected. Also, check for vacuum to the front axle.
