2007 Dodge Ram 1500 hemi my 4 wheel drive does not engage after turning the switch to 4 wheel high or low I hear clicking under vehicle but does not engage

Remove the actuator motor assembly from the transfer case and try to manually engage the transfer case, if it is easy to engage then the actuator is the problem.

Can a Dodge Ram 1500 4-wheel drive vehicle get stuck in 4-wheel drive mode during extremely COLD weather?

Yes. The actuator motor can get stuck on the transfer case. You could wait for warmer weather or try tapping on the actuator with a hammer, lightly, to get it to disengage.

On my 2006 ram when I switch it to 4x4 the light flashes on the dash for about 10 minutes before it turns solid and 4x4 finally engages. This truck is new to me and I have only tried this shifting in -15...

The warm garage check is not a bad idea, all in all if it still doesnt work you have a bad front axel 4X4 solenoid (POSSIBLY). Also check your differential fluid and your transfer case fluid. Old dirty fluid will cause the four wheel drive to be sticky and not engage properly. If the fluid is dark at all, change it ASAP. Good luck.

1996 dodge ram 5.2 auto 318 to shift to 4wd do u put in park or drive and can you shift to and from 4wd on the fly

Need to know what transfer case it has. Most t-cases have synchronized gearing...meaning shift on the fly. A quick test is drive at less than 5 mph, and shift, no gear clash means you have synchros. ****This is only from 2wd to 4 high. 4 low you MUST be stopped(doesn't matter what gear its in).****

You need to find out what code it is setting that will make it easyer to find out what is going on. You need a true OBD II scanner to do this. I have had the problem with this same intermitant light. You can check to see if the transfer case wiring is rubbing where the wire go around the trans

2006 dodge 5.9L cummins auto 4wd when i start the truck srv 4wd sometimes comes on but you can hear the 4wd try to kick in. when driving down road it will randomly try to kick into 4wd. on time it...

Most likely the motor on the transfer case. You have several modules/computers that work the transfer case shifting. Since it is trying to shift, it narrows it down to 2 modules. The transfer case module and the motor module(the motor has a module built in). I do diagnostics, I have the tools to do it. I eliminate other possibilities. Wires and such. I place more motors, than all the others combined. It is the most abused electrical part of a 4x4 vehicle. And it is on the bottom of the vehicle.

Transfer case wont engage

shift into 4wd and move truck a couple of feet.
if light is still off, park truck block the wheels set the park brake jack right front wheel and try to hand spin the wheel if wheel doesn't turn 4x4 is functioning properly but there is a wiring problem use an ohmmeter to check the 4x4 switch wiring fuse and bulb
if wheel turns freely the front axle or transfer case is not engaged
attempt to hand spin the front driveshft if the driveshaft will spin the transfer case is not engaged check the transfer case shift linkage, problem is in linkage or transfer case internals
if the driveshaft will not spin the transfer case is engaged properly
with trnsmission in neutral or park start engine measure vacuum on the two vac lines at front axle shift motor . one line should have approx 20" vacuum. other line should have none
if no vacuum measured look for vac leak or bad vac switch
if both lines have vac look for a bad vac swithc or ruptured cad actuator diaphragm
if one line has 20" +- VAC
move transfer case lever to 2wd measure vac again lines should have swapped vac signals
if no vac switch bad or 4wd shift likage needs adjusting
if yes vac motor bad or stuck or shift fork stuck
remove vac shift motor from the axle attach vac lines to shift motor engage disengage 4wd
does shift motor plunger move at least 1/2 inch
no shift motor bad
yes check axle shift fork and vac motor for binging
