1991 Dodge Grand Caravan Questions & Answers
Cabin heat
Yes, it might be hard to find such a diagram. Short of a factory service manual, I don't know. Perhaps a friendly parts person at a Chrysler dealership might be able to provide you a copy of how the vacuum lines connect, and how routed.
What you generally have is a single vacuum line from the engine going into the firewall and under the dash to the rear of the heater/AC control assembly. The line enters a fixture that can distribute vacuum signals through several hoses. One of those is the hose to the water valve, the only vacuum line that goes back into the engine bay. Selecting heat on the control obviously will send vacuum from the fixture to the water valve. The other hoses or lines connect to diaphragm operated door levers to control where air is sent.
See where the vacuum line for the valve goes back into the firewall. Then get on the inside and try to find that line-it may have broken or come apart. You may need to pull the heater control assembly out to get to the podlike fixture that the vacuum lines sprout from.
An alternative in this frigid weather, a make-do temporary fix, is to tee off a manifold vacuum line from the engine, and run a hose to the water valve. It will be on constantly, but it's winter, hey?
My 91 dodge caravan slips when shifting from 2nd
Once unit is sliping, it's at the point of no return. Depending upon how bad it is and how long it's been doing that, sometimes you can use lucas sealer and conditioner to prolong the end a bit but best is to have it rebuilt or replaced.
How do I flush the heater core in a 1991 dodge
first it is a waste of time, buy a new core and install it. if you like tilting at windmills, remove the heater hoses from the nipples protruding through the firewall, ,hold the end of a garden hose over one open nipple and have someone turn on the hose. move the hose back and forth from one nipple to the other a few times. the grime you are trying to remove has melded itself to the core and for the most part will not be coming out. costs nothing though so does not hurt to try. you will have antifreeeze dripping all over when you take the hoses off so have something to collect it.

Car loses acceleration, starts bucking, then
The sound you describe sometimes happens when you have a plugged catalytic converter. You could remove the converter and drive it to see if the problem goes away or you buy a pressure test kit to check the pressure in the exhaust system upstream from the converter. If the pressure is higher than allowed you have a plugged converter.
