Someone posted a link that had the HVAC channel list and operating instructions, 
I somehow deleted this email and can't seem to find the link. Could someone be 
so kind and send it to me? Thanks,

Elijah

Elijah,

Like Elvis, I'm just catching up your thread so I may repeat other
suggestions:
- Temperature Flap: Check if the new one is moving, either visually or through 
the HVAC (Channel 8, 9 or 10, I don't remember exactly). Visual inspection is 
preferable as the link may be disconnected.
- Temperature sensor: Check the channel 51 on the HVAC head unit to make sure 
the engine/hvac temperature sensor gives approximatively the same reading as the 
temp gauge on the dash. If the temp sensor is always giving a low reading, the 
temp flap will never be activated. This sensor is on a hose between the engine 
and firewall (blue plug).
- Air trap: Make sur there is no air in the system. There is a small vent on one 
of the hoses on the driver side of the HVAC box, between the firewall and the 
windshield.Open the vent when the engine is warm and make sure coolant is 
flowing out of the vent.
- Coolant electric valve: There is a valve on one of the hose going through the 
firewall. I _think_ the valve is between the engine and the firewall, below the 
engine/hvac temp sensor but not sure. Check if it works.
- Heater core plugged: Last check because it's quite a mess. Disconnect the two 
hoses going through the firewall (the best place to disconnect them is between 
the engine and the firewall) and plug a garden hose to one of them to check if 
the water is flowing freely through the heater and hoses. Open the water slowly 
as the heater core may not resist high pressure if it's not in good shape.

If you don't want to see all the coolant flowing on the floor when you 
disconnect the hoses, remove a gallon of coolant through the purge plug on the 
lower passanger side of the radiator.

As you get a little heat instead of no heat at all, I would suspect a problem of 
coolant flow, either the valve a plugged heater core/hose.
That's about it for now.




Vincent.

Ok, this is getting old and the pregnant wife is getting a little tired of 
heating the car with the heated seats. I replaced the heater flap motor and also 
the vacuum actuated valve and I still have no heat coming through the any of the 
vents. If I put the fan on the lowest setting the air comes out warm but if I 
raise it at all it turns to cold. What else could cause this?
Any help greatly appreciated.

Elijah
