2000 chsvy venture poor heat

Unread post by joewood » Mon Dec 01, 2014 10:57 pm

2000 chevy venture heating problem. I have a 2000 Chevy Venture not putting out heat. The coolant level is full in the radiator and the reservoir. Not losing coolant, so I'm not suspecting head gasket. there seems to be some sort of valve going to the heater core (a solenoid of some kind? ) on the upper right side of the motor near the coolant reservoir. One side seems to be hot, and the other side doesn't. It has 2 hoses attached to it. I bled the system by opening the bleeder going towards the thermostat, but haven't gotten any kind of respectable heat. The temp gauge will go up to and hang out about half and 3/4 and gunning the engine a few times drops it down. I don't know if the rear heat is attached and working, but also the indicators on the control panel on the dash when switching from face, face/foot heat to foot/defrost or any other variant goes from inside air to outside air light on the panel without changing it myself. when moving, temp gauge drops down to about 1/4 but that would be expected from airflow over the motor and cooling fins of the radiator
I have considered running a piece of pipe to the two sides of the solenoid/valve on top of the motor near the coolant reservoir and bypassing that valve to see if that works, but not sure if that would be the problem and if that needs to be replaced, but I don'e get a diagram showing that valve
