HEAT
No heat comming out of the vents. Replaced the blower last year and it is working fine at all speeds. no hot air out of vents and the air that is exiting remains cold, also there is very poor flow even when the defroster is enabled.Any help/ suggestions/ replies are appreciated.
Thanks,

There is a "bleeder" valve located on the passenger side firewall near the heater core that is probably stuck shut.

Hey C43:
Did you ever solve your no heat problem? Sounded like a bad duo-valve to me. I have a similar one, only no heat one one side. Both heater core sensors are showing similar readings so I don't think it's my duo valve.
Thx,
Wade
