The ac works fine, haven't tried the heater as it's been hot. I have tried to backtrace this line and I lose it under the cowling. The transfer case also has a green line into it.Same one?? No 4wd problems that I know. Is it a vent??

Vacume line diagram for 2001 dodge grand caravan looking for the line that runs to the ac / heater,


It sounds like vacuum is not getting to the vent, heat and A/C controls. Find the vacuum can. It may be under the hood on one of the inner fenders. Trace the lines back to the vacuum block at the intake manifold or fire-wall, and also back to where the line goes thru the fire-wall. Check the can for leaks or obvious holes. They used to be just a plain metal can, but it could be a plastic ball. Check the lines as you go for breaks and rub-thru's. Move the controls thru all settings and listen for vent door movement. (Run the engine momentarily to build vacuum in the system.) Worst case is a bad vacuum motor or air flow position selector switch.

The air blows mainly out the defrost and lower feet area with a little out the vents.... no matter what setting its on.... whats the problem here


It's most likely a vacuum line, look under your hood (close to the cowl panel) for a disconnected, cracked or broken vacuum line.

In some rear cases, it could be the vacuum switch (in dash). Or vacuum diaphragm (under dash).

Hope this helps you ???

I have a 2000 Durango and the air is blowing through the defroster vents when the air is turned on rather than through the AC vents. How do I correct this?

1995 dodge 3500 4wd wont engage have shifter on floor light wont come on or 4wd wont engage


Any time your dealing with a 4x4 system the best start is at you front axle. Its primarily a vacuum leak so check to see if the 2 vac lines are hooked up (its good to check the electric connections.). When your 4 wheel drive is engaged and the motors running you should have vacuum at one or both of thee lines depending on if your in 4 hi or low .
If no vacuum at axle check the Vacum switchs(the plug with 4 vac lines) on top of the transfer case it will have 2 feed lines(grey & green) they conect in to the into the vacum harness on back of motor (passanger side). A vacum schematic is normally located on the raditor core support (right under the hood next to hood release)
Hope this helps

If you look under your hood, there should be a sticker that has your vacuum hose routing on it. If not, what size of motor do you have?

May have a vacuum line leaking, engine light comes and said it was gas cap, replaced that and it still comes on. how many vacuum hoses are on my ram? Dodge Ram 2001 club cab magnum engine.


Many vacuum lines, but if it indicated a bad cap it should just diagnose the fuel vapor system. Your unit is 8 years old. Check the filler tube to see if the hose clamps rusted off. Being a bearer of bad tidings it could also mean the tank is rusted and has a hole in it. You can check the vapor cannister under the hood, your PVC valve, and vacuum hoses under the hood. Radiator shops can repair gas tanks and they should be able to pressure test your system on the vehicle without taking everything off.

When you go down the road my a/c goes to defrost


Try to locate little check valve in vacuum source line, it may be faulty. Sometimes hooked up near/at brake booster. You may have to follow vacuum source through firewall to back of controls to find it. They used to install one under dash between firewall & control, but they moved it I believe, so following vacuum line, should locate it for you. If all checks out good to control, you'll have to follow them down to heater duct to locate leaky hose or malfunctioning vacuum motor.
