Dodge CaravanThe Dodge Caravan is the best selling mini van from Dodge. How many Dodge Caravan owners here at DodgeForum.com would agree? Discuss it now!
on this van when you swith the vents from floor to def to vents it uses vacuum. I noticed when using AC that when I accelerate, not even really hard just like climbing a hill on freeway it acts like it looses vacuum and switches down to floor as soon as I let off accelerator it switches back to vent. Is there a Vacuum can like some of the other vehicles have to store vacuum?? if so where? I cannot find anything like that in schematics. I cannot find a vacuum leak anywhere. does anyone elses do that or is mine having an issue I had a Jeep that did that but my vac can broke(plastic ball) and i had to bypass it so I imagine it had no stored vacuum.
Easiest way to trouble shoot this is to use a hand-held vacuum pump and attach the hose directly to the vacuum motor that controls the air "mode." Apply vacuum and see if the vacuum motor holds the vacuum. If it does, then you'll have to test the vacuum line from the switch to the motor. Work your way backwards until you find the component that leaks.
oh thatks can I just go to a dodge dealer and get that or will I have to buy it? is it the one that connects to the vacuum tube on the break booster? i see what looks like a ck valve there
ok what I was wondering is I got a paper from the dodge dealer here in town about something to do with the wiper bushing and it is covered by dodge all i need to do is bring the van in I have to pay nothing I was wondering if that vacuum thing was one of those also.
I musta mis read it I was sure it was a recall for some bushing on the wiper arm maybe it was something else. I just thought that maybe the vacuum ck valve was a free fix like the other one.
