Rear heater hose hook up?

09-29-2006, 05:38 PM
I have a 92 suburban with the rear air. I noticed last winter that I had no rear heat on a/c. so this summer I noticed that where the heater hoses hook up one of them is not hooked up. I need to know how to hook the heater hose up. Looking at the conections the one on the right side(engine) connects to the engine. Middle one goes back to the radiator. Now the question is the one on the right where does that go? Is there a tee I need? I just don't know.

I suggest a trip to the nearest u-pull-it yard. There you can take a look at one (and probably acquire any needed fittings) without having to do anything to yours until you are confident you know what the arrangement should be and that you have all the right parts. I'd also suggest you plan your hookup in tandem with a coolant system flush so you'll just have water in there; that hose may have been unhooked to compensate for a leaky heater core and it would be unfortunate to waste good coolant to find that out. Good luck!
