No heat and a cold running engine
I was wondering if anyone has had a similar problem? I have zero heat. And living in Michigan this made for a rough winter. The temp also seems to run a little cold. A dealership spent two days trying to solve the problem and couldn't so just wanted to know if anyone else has had a similar issue.

is your heater core clogged?

whats the part about a cold running engine.. did the dealership give you an actual temp from their scan while it was running...???

you know i had the same issue and i have the same vehichle. not sure if its the heater core but i am sure the dexcool has it all clogged up, i still have to look into mine. waiting for it to be a little warm so i could do a flush, but i might just take it in and have one done.

Hhmmm. An actual Chevy dealership couldn't figure out why you had no heat? What does the coolant temperature gauge read at?

What did they call cool and what conditions was it under when it was called "cool"? It does seem like the heater core is clogged though it also seems to be a very common problem. I haven't had the problem yet knock on wood.

If you didn't say the dealership had it i'd suggest the thermostat. I had one stuck open on my 89 Jimmy and it caused the truck to run cold and it took forever to get any heat in the cabin, and it really wasn't that warm when i did. I would think they would check the thermostat... if not it's a pretty cheap and quick thing to try.

thermostat would be the first thing i'd check.

I basically had the same problem. I had no heat. I had the thermostat replaced, and I noticed that it wasn't warming up all the way, plus I had no heat. I got the heater core flushed, and I had heat again for a few days. The problem came back, so I ended up getting the heater core replaced, which was quite expensive since the whole dash had to come out. Since it was such a hard and expensive job, I told my mechanic to order an AC Delco heater core, cause I wanted to make sure that job would not have to be done a second time. He also flushed out the whole coolant system, and filled it with DexCool. When I got the truck back, the heat was like brand new, and most importantly, I noticed that the temperature needle went up to where it was supposed to be, and it would warm up a lot faster. I haven't had any problems with that ever since.
Try having the heater core flushed out, and see what happens. That would be the cheapest approach in my opinion.
