Heater issue...someone help please!

ok i let it idle like you said and there was lukewarm air but it didn't change when I drove it it stayed the same temp.

Unplug the water valve and see if you have better heat.

You can look at the RealOEM diagram and see that it is the lower pipe. Very easy, just un-do the plug at the top, it gives it power. But when power is off, the valve is supposed to be open. It is an easy way to check if it is not functioning.

i'm having a similar problem, how did ur no heat problem turn out?

well I figured out it wasn't my heater core because there wasn't a sign of coolant anywhere...but the blower went caput. now I am driving with no heat all.

im waiting for some loot to come in so I can get a new blower as I can't just pull one from the countless us-spec e30's in junkyards around here
