What would cause van not to go in snow anymore?

Most Likely it's your distributor cap. if it's slightly loose or has any microfractures that you can't see, moisture gets in there and wreaks havoc and causes the spark not to be distributed. try a new distributor cap they're fairly cheap, probably somewhere between 10 and 30 dollars

You have an intermittant problem with the stability control that has to be addressed at some point and that would be a good time for them to inspect the suspension for anything that could be triggering those symptoms.

Sorry no idea iam not a bodywork man but couldnt you repair it with a tub of fibre glass ? Maybe try a scrapyard ?

You could have damaged the crank posistion sensor or the wiring to it.

maybe a vacum line has come off.

I'd say the linkage is a little bit off and the shifter is not quite putting the linkage in the park position. To confirm this you might try pushing and or pulling on the shifter a little bit as you trying to start the vehicle.

With all due respect, what the H___ are you doing driving in 2 Feet of SNOW? The rumbling noise you hear is most likely caused from Snow being impacted in the CV Joints, Wheel Wells and anywhere else from freezing in place after driving in the "Deep Snow". The solution is to have the care raised on a Hoist and Pressure Washed to remove all Snow and Ice from the the entire Bottom Side of the Vehicle. It then should be allowed to dry thoroughly in that building before being driven. Additionally, if any noises occur upon exiting that facility turn around and have it repaired before it costs you untold thousands of dollars to repair.

Next time you have "DEEP SNOW" wait until the Roads have been cleared, salted or sanded and are back down to pavement before driving on them.

Not sure why but the only thing that keep the belt on tight is size and a good tensioner. You may need to replace both the belt and tensioner to fix this condition.
I have seen this condition before on chrysler/dodge vans

obviously the bolt needs to come out did they try to heat the bolt up or not ? the only way to properly align it is with the removal of the bolt correct as it rely on caster camber settings so maby a more well known repair shop is in order

ESP is the Electronic Stability Programme - it only comes on if the engine computer needs to make adjustments for poor driving or road surface conditions. If it is on all the time (and you are not driving down a country road) then you should get it checked out.

P.S. Sometimes low tire inflation will cause the problem. Winter tires depending on the tread will also cause this error.

Take to a local parts store and have the engine code read. Could be a multitude or combination of different problems.
