You are in the Chevy Venture
What is this discussion about?
Chevrolet Venture, Heating / Cooling, Van
Sep 16, 2010 (6:52 am)
I own a 2003 chevy venture and I am having trouble with the fan. When I have the settings set on vent and the heat turned to max and the fan to number 5 setting very little air flow comes out of the vents. As I turn the heat control to the cool setting the air flow increases. Max. air flow is when heat control is set to max. cool setting. Why?

I am actually having the same issue with our van as well.
You can hear that it is switching from cold to hot, and when you put your hand on the vent you can barely feel the hot air coming out. I then turn the temp to cold and you can hear it switch and it flows out pretty good...(almost too good).

When trying to drain the radiator on my 2000 chevy venture, the valve just turned and turned with no coolant coming out, Then the whole valve suddenly came out completely. When I put the valve back in I cannot tell if it's actually secure as there are no threads or anything. It actually looks like a plug with an O-ring on the end.
Is this what it is supposed to look like or did I break something off of it when initially trying to unloosen it? If it's normal how does it stay in?

I'm new here.
I just bought a 2003 Chev Venture from an Autobody shop. They had fixed all the problems and got it safetied. I have the paperwork and everything. One thing I noticed when I'm driving the van...
When I'm driving long periods, the heat is working, very slowly...... but when I'm driving short periods. I get no heat, even when I stop at the lights, the heat cools off and it feels like it's blowing A/C. Mind you, I live in Winnipeg and it'll get dang cold in the middle of winter. Considering it's almost Nov and it's getting colder. I was wondering if this is an easy fix that my hubby can do? Or is this a normal thing??

check coolant level, in Radiator FULL and proper level in overflow bottle as well. make sure hose connects overflow to radiator cap,
,,check or replace rad cap 14 or 15 lbs, or swap with another car
You must have 50/50 fluid ,,protected to like 40 below F.,,,i am from MN and it get cold here as well.
there is also a burp screw on top of the manifold to let air out. open it and when solid fluid comes out close it. look at owners manual i believe it tells you about it
other than that the thermostat is not that hard to replace in case it's stuck open when done need to burp it.
Can you feel the hoses going into the heater core ,,,is one very hot like you can touch it for a second and you must let go and the other cool ?
I can't recall what changes it from hot to cool,,is it cable operated ,,,gotta SEE FEEL , TAKE APART stuff underneath until you get to the air blend door to see if it's moving fully from hot to cold all the way.
I personally went a junk yard and took one apart.1st. then took mine apart for water leaking into operator AREA from air conditioning,, i could get all they to the heater core it was not hard but a bunch of stuff needed to come out and GO BACK IN The SAME WAY
put a temp gauge in the a/c vent outlet and have it blow out at operator like you would on A/C it should at least 140-150 degree F it is just sitting there the stat could be good
do the cooling fans run when you turn on A/c ?
are the cooling fans on all the time, i assume you don't have the rear coolant heater option

Did you look in ownsers manual?
Is there a code on for check engine light
Collant leve in rad has to be up and the overflow tank needs to be at proper level KEEP an eye on the leve every time you open the hood of lack hot air.
I would syas you need to bleed the one or two screws on top of the engine ( to purge the air and get a solid stream of collant ,,and it should be a 50/50 mixture, once you do that then make sure the system is full again.
I would look in my owners manual but i's not handy and or look under the hood to see if there are two blled screws or just one, I think tow and they look alike. as i recall you loosen them with engine running and collant and air come out (it's easier if you do not remove them completley) that should help you out.
I didcovered the problem when i changed my stat.
<<< also feel the hoses especailly to and from the heater core if one is hot and the other cool it could be a heater core issue,, I assume you have a working cable ( i think that adjusts a door form hot to cold) this is likley not the answer i you had temp heat for 2 days..unless you moved the air blend door in conjusction as to wehn you had heat. ... Heat in my vneture gets very hot needs to be turned downafter you get going, and seems very hot in summer and my CD's a very hot to the tocuh. SUPER HOT almost to the point you don't want to tocuch them. Not sure if that is heat related however. ~~ lots of luck If you can't find bleeder screws ask a mechanic type person or if needed write back, sorry for the delay,

Did this harness problem relate to the blower motor resistor problem? I have some of the same problems in the same van. Passenger side window will go down from the driver side but not up. The drivers side window seems to have intermittent power problems. The heat only works on 4,5,6 nothing on 1,2,3. Should I be replacing the blower motor resistor first or going after this wiring harness on the driver side?
