I have a 2nd gen truck.
1999 1500 ram basic 2w.
No cruz control.
No power windows.
Got mirrior heater.
Stuck in defrost mode.
Good from motor vacuum port to the canister under the cowling (-4hg)
Found a tee with a dead end (1/8 in tube brittle and crumbing) in path between motor vacuum portand canister.
I can not find the open end .
The vent control is vacuum powered.
The dash mounted vent control has colored tubes.
Which I have determined are good to each of the vacuum motors.
The Black tube is vaccum supply.
WHERE DOES THE TUBE GO THRU THE FIRE WALL.
LOOK FOR ME. ITS THE TUBE ON THE PASSANGER SIDE.
NOT THE TUBE AT THE TOP, THAT GOES TO THE CANISTER.
LOOK FOR THE TUBE OFF THE TEE BETWEEN THE CANISTER AND THE MOTOR PORT.



THANKS bbgundave the lost.

 

Pics, I've replace almost every tubing i could find.

 

You forgot the magic word, but I'd look anyway if I had a truck and not a van.

And pics would be extremely helpful. You have to put them online somewhere first, then link to their URL.

 

+3 on pics. My truck is similar to yours but with power items you lack. But for me to climb around based on description, I may look right at it and not see what you need as I would have described it differently.

Also, adding truck info in your profile would make it easier for others to know about your trueck (engine, trans, etc) without you having to retype that every time, possibly leaving out info that would be helpful.

So if you can post some pics, I'll see what I can find for you.
