No heat, bleeding coolant line

[iksnoved25]

Long story short. Took car to shop to fix j plug. Got car back with no heat. Took it back to shop and they flushed heater core. Heat worked for 200 miles. Next day it didn't.

Please help... Thanks!!

When i crank the fan up, it gets colder. Medium fan = more heat at idle. Is this normal?

Sounds like you have an air bubble in the heater core.

Damn, still?! Should it be spraying up from that tiny hole the whole time when the hole is exposed?

Yeah, at idle it with fan cranked up definitely isn't as hot as when fan is at medium.

Yes, you should get a steady stream once the air bubbles are gone.

I've got a steady stream now...but should that coolant coming from the hole be warm?

I Let it stream steady for close to 10 minutes. Put the hose and clamp on and heat seemed alright for the next 25 mins. I Had it blasting on high on the drive home, and I was pretty much sweating. Hopefully whatever it was is finally sorted. I still have no clue what I did differently that time compared to all the others. Guess we'll see tomorrow morning if I get heat

Okay, so I drove to work this morning (30 mins) and the heat was hot as hell. As in "LOW" was cold, and 64 (next step up) it was hot. Almost like there was no middle ground between Low and High. Assuming air was in the heater core, which has now been bled, would this "new" issue now be the thermostat?

You should probably scan the HVAC module for codes. There's a possibility one or more of the flapper doors are not functioning correctly.

I just came across some threads about just that. I hear replacing the motor is a PITA requiring you to remove the dash.

The flappers are under the glove compartment. You don't have to remove the dash AFAIK.

Thank you both for the info. I think I may download that VAGCOM lite to at least scan the codes to see what is thrown. I think I had two problems... (1) Air in the lines (2) Flapper motors not working. That would explain why last weekend when I drove it after getting it back I had to have it on like 64 or Low just to be comfortable. I noticed the lower temp was hotter than what it should be. It was difficult to find a comfortable temperature.

The driver's side temperature control motor is by the gas/accelerator pedal, all others are behind the glove box. The one on the driver's side is a HUGE PITA just so you know.

Try resetting the servo motor adaptations by running Basic Settings in measuring block 001. Doing this will often resolve servo positioning errors, restoring normal operation for awhile at least.
