THE HEATER WILL ONLY RUN ON HIGH SPEED

that's internal engine repair so if you are not a mechanic you probably want to take this to a professional.

get fuel pressure gauge ASAP. replace lift pump with after market one (not in tank from dodge..junk)

P1596 Speed Control Switch Always High,
you should take it to a chry dealer

the idle air control is on the back of the throttle body. it has a plug going to it and is held to the throttle body with 2 screws

you going need a scan tool, this tool is also able to tell u what causing the code.

get the belt routing from the local dealer.
they will not charge alot of money for a reprint from the factory service manual.
also
dayco belts come with the belt routing on the box.

Bring it to a parts store, most will scan for engine trouble codes for free. They will plug a hand held scan tool into the vans diagnostic port (under the dash) and 'read' codes stored in the van's computer. They can tell you what the codes mean, and suggest how to fix it. If you have any further questions at that time, post them here with the code #'s. Good luck. Curt
