Replaced Heater Core still NO HEAT!!
I have a 1992 volvo wagon 740 and I have not had any heat so I replace the thermostat and that was not it so I replaced the heater valve and that was not it either. So I took the plunge and I replace the heater core and I still don't have any heat. I think it might have to do with the vacuum lines and the dampener doors but I am unsure how to check, so if anyone could shed light onto this subject it would be greatly appreciated. THANKS

Yeah, there's lots of 'em in JY's...but if they rarely go bad I wonder why LKQ sent 4 different units to the shop before one worked? Or the one in my 91T that was bad? LKQ sources parts nationwide...wouldn't think geography or climate would particularly affect longevity. Heck, they're 20 years old. I have a 2002 Explorer w/ similar stuff that didn't last 5 years.

well ok, rarely is a relative term but 4 out of 4 being bad, that's pretty bad odds, no? in my experience, they are pretty bulletproof as far as those kind of gadgets go... generally u don't hear too much about those things being a problem. and if u go the new route, i believe those things are like $700... btw, what does lkq get for them used?

Vacuum Works
Well like swiftjustice44 said I have positive airflow and I can change the direction were I want the air to go wether it be defrost on the lower vents or the high vents and I was wondering is this just hooked up to the vacuum lines and separate from ACC circuit board. Or in other words could the vacuum controlled dampener doors still change if the circuit board is bad. By the way when I change it to heat I do not hear any vacuum lines or and dampener doors opening or closing. Thanks
