i have a 97 dodge b3500 15 passenger

New Issues: (any help is appreciated.)

Found this connection below the passenger side headlight, behind the panel i had to remove to get to the vacuum reservoir.



if you cant see the colors on that connection
it goes from left to right:
BLACK, BLUE WITH RED STRIPE, GREEN WITH RED STRIPE, TAN WITH RED STRIPE.

It also says 52772 B-14 on that side of the connector

and on the bottom it says 4 8 2 1


we named him Hank.

Fixed:
Windshield Wipers
Air Vents

 

You'll be replacing the switch or the motor. The only way to know which one is the problem is to take power readings when it's not working. If there's no power to the motor, the switch is bad. If there is power to the motor, the motor is bad.

 

okay, im really new to this van thing.
so where can i find the switch and the motor?
do you have any pictures of them?

 

You don't know where the switch is to turn on your wipers?
I think we just found out why they're not working!

 

edit, double post sorry.

 

oh crap! i thought you meant there was some other electrical switch somewhere haha, no i know where that switch is

but you could you tell me where the motor is?

 

It under that plastic trim piece the runs along the bottom of the windshield. You'll have to remove the big rubber seal, the wiper arms, and a bunch of screws to get it off.

 

got some updates in the main part of this topic.

 

Working on an A/C system is kind of like playing handball against the drapes if you don't have the proper equipment to work on it. Other than buying a couple of cans of R134a refrigerant and giving it a charge to see if it holds, you're kind of stuck bringing it to a shop.

The defrost/vent issue is typical of when the vacuum for the vent controls is lost (broken or disconnected vacuum line). The vacuum line starts at the passenger side of the intake manifold, then runs up to the vacuum reservoir (round black ball) under the passenger headlight. From the reservoir a second vacuum line runs up and through the firewall to the vent control switch. Defrost is the default position of the vacuum actuators inside all of that ductwork under the dash. That's why a loss of vacuum will result in only having defrost.

 

thanks alloro! found the hose that was disconnected from the vacuum reservoir and i attached it and the vents started working! thankyou!

but when i took off the little panel that i had to remove under the headlight to get to the reservoir, i found this set of wires and something that has been disconnected.

pictures of the connection and the description of wires are in my main post.


thanks again
