Heater prob.

[GrandAmSE]

Ok the problem is the same as someone else had. The heat only comes out the floor vents. I know its the line going to the vaccum ball. Problem is it broke at the T fitting and the other two line coming out are disconected. Where do they go? I have new line so I just need to know where to send the lines.

Did you locate the 3-way check valve? Click on the pics below (they're huge)

It broke inbetween the 3way check and the T fitting. Where does the Cruise control line end at?

[DiscoStudd]

What year is your car? If it's 88-93, the line goes to the cruise module/servo's vacuum diaphragm. If it's 94+, then disregard that part because the cruise module is 100% electric and doesn't use a vacuum diaphragm (and there won't be a "T" fitting there.)

[GrandAmSE]

The cars a 92 but the engines a 94. So I should discard the T fitting and run 1 line from the 3 way check to the vaccum ball?

[DiscoStudd]

Yeah. If you don't have a vacuum cruise module, then there's no reason for a T fitting there...

[GrandAmSE]

Thanks.

[DiscoStudd]

You bet! Let us know how it works out...

Hmmm ... this could be the reason why I have no cruise and the heat only comes out at the bottom vent and slightly the windshield vent.

[GrandAmSE]

The line alot of the times gets smashed by the battery.
