Need to fix my HVAC controls

[Kalgorn]

Guessing it's a vacuum line but I'm not sure. Where am I to be looking for this vacuum line(s)? I remember reading something about the vacuum ball and it being in the driver's side fender (I think). Anyone have any pictures or something that will aid me in this?

look under/around the crusie control servo, thats usually where they break. in my problem, i was missing the entire line to the checkvalve for HVAC/Cruise, so just check around

Sounds like a good place to start because didn't you mention your cruise doesn't work either?

[Prospeeder]

most people dont use there cruise if they lets say live in the city, i didnt know mine didnt work till some1 told me to look

[digitaloutsider]

It's most likely the vacuum check valve under the cruise control module.

[Kalgorn]

Alright, thanks guys. Yes, the cruise doesn't work either. I'm gonna check it out this morning before work.

[Kalgorn]

What is this thing and is it supposed to be broken?

 

This is the bottom vacuum line (the little one) on the cruise control module. Comes down to a "T" and this is what I ran into. Not sure where the left runs but why is there nothing on the right? And what is it SUPPOSED to run to?

 

 

 

I'm actually sitting outside at my car on my laptop using the internet. Feel free to IM me and try to work me through it.

[Kalgorn]

Alright, not at my car anymore. It looks like it's about to rain so I'm done for now. Found this new gem though. Not sure if it's supposed to be connected to anything or not... what do you guys think?

 

 

Also, the top vacuum line on the cruise control module is very dried out and cracked from being bent. Could this cause a leak? The hose basically rubbed off onto my fingers. My hands were black after messing with it for a little while.

[Prospeeder]

that T is definatly a leak, go to a j/y and find the vacumm harness from a Gen 1 w-body, and change the T and all, thats what i did, lol, jacked it from a 3.4 DOHC GTP

[Kalgorn]

Where do the lines from the T run and how exactly do I replace just the T? I can't see where the left line is supposed to go because it runs under everything else and I obviously don't know where the right line runs.

[Prospeeder]

well, look at a j/y car, and find out where it goes

I think that plug is for the hood light. It seems like it's in the right spot in the engine bay. however I could be wrong.

[Prospeeder]

well start the car, and see if it sucks ur finger, get some carb cleaner or somthing and spary it

Definatley a possibility. It's in a spot where it would reach the hood perfectly fine and still have movement.

Are you talking about the side of the T? I tried that. Didn't feel a thing but it could be sort of gunked up from whatever WAS in it.

[Prospeeder]

hmm, is it even a vaccum line? or anything? u can tell somthing was there, where is it? ill look for u when its not raining

I'm pretty sure it's a vacuum line. It's the bottom line off of the cruise control module.

 

I appreciate you looking for me.

That plug you were showing goes to the black box where your air filter is. Its a black box with the snorkel going to the intake plenum.

[Prospeeder]

mine will be easy to find the T, cause my vaccuum stuff that was under the cruise i moved above it cause im lazy, lol
