My van had no heat. There was a repair made on the coolant tube that runs under

I actually pinched off those hoses right at the tees, I've been driving for quite a while like this now, trying what you just suggested and still no heat, could it be the water pump? And how long does it take to get the air out? Let me point out that it did have heat before the repair was made

Sure the heater control valve is correctly installed.. If you had heat before...concentrate on last work done !!!!.. Don't start blaming other componets..

I didn't see a heater control valve, where would it be? And the work that was done was by a supposedly good garage

Take it back and let that shop fix it!!.. That's just how it's done!.. Can't leave a customer without heat!!!

Yeah I know, but he is saying it's not his fault. Plus his shop has been closed since Wednesday. I've had to drive in a blizzard w no heat or defrost in the meantime
