#50 of 101 Air Conditioning is anemic, but works. Why? by fleastiff

Jun 27, 2009 (5:24 am)

I have a 2000 Chevy Venture. At first I was rather well impressed by the air conditioning system. It worked and it seems to have worked quite well. In Florida, this is a much appreciated feature!
After a while the AC seemed to get weak. One mechani re-charged it. Yet its never really worked anywhere near as well as it did before. Its set on taking outside air and cooling it. Would recirculating the air make more sense?
Its not that cool air is not coming out of the vents. It is. But its cool air rather than cold air. And it seems to be less strong a breeze even if I have the fan set at 5, its highest position.
What items should I check to see why I'm getting only cool rather than cold air being blown out of the vents.

Did u ever get any answers as to why your a/c wasn't working well - mine doesn't get as cold - and it doesn't blow as hard - i'm about to have some freon put in it, but i've also noticed water in my front 2 floor-boards (soaked thru carpet) in conjunction with running the the a/c for long periods of time - which is unavoidable in the SE during the summer....

Your floor boards are wet due to a pinched drain hose. More times than not you need to replace the hose. It is a flimsy hose that kinks easily. I have had this problem several times and it goes away when the hose is unlinked/replpaced. Good Luck.

2002 chevy venture AC drain water LEAKS into passenger feet area under carpeting.
How did you solve it. i blew backwards with a tight blower nozzle connection into the Ac drain (short little tube that drained behind the engine just below the alternator. no water came out and the van was sitting on a level garage floor.
 
Did anyone solve the problem without taking the entire a/c plenum apart and clean out muck ?

I can't imagine there is a pinched hose or where it might be, I blew air into the drain hose coming out of the a/c box behind the engien jsut below the alternator. what di you find and how did you fix it ?

I have the same problem with my 99 olds silhouette. The drain tube no longer, or never did, extend through the firewall. This summer, with more than usual use of the A./C we found the pooling water in the passenger footwell. But this problem has obviously been there a long time as wires are rotten and footwell is rusty.
 
I tried to get some help from GM to no avail.
 
I need to somehow get the tube to extend back through the firewall so that the water drips into the engine compartment and not into the cabin
 
Anyone got any ideas how to do this?

all the sister chevy Venture, Silhoutte, Montana have a rigid box that contains the evaporator ( little radiator) that gets cold and the air blows thru it to A/C (cool) the inside air. (it is major leauge buried up in the dash)
 
On the bootom of this box is a molded in plastic rigid tube that extends through the sheet metal body and the rigid tube runs into the engine area & it's suppose to drain out any water into the engine compartment kind of behind the alternator.
 
i have a junk yard by me and if the engine is out. then the tube is very visible,,it's not flexible and almost impossible to damage or misroute of have it fall of or something ( unles it's a nasty smash up. likley total the VAN).
I basically learned that it's likley that some of the prtoective non absorbant foam stuff might have moved /shifted and may be clogging the outlet tibe hole so that the water doesn't drain out.
 
If you know how to add pictures to this site PLS let me know how to do it, i took a few with cell phone that shows a cut away.from a junk yard vechicle.
I am looking at likley adding a hole on the drivers side of the box not to bad to get at that side, and then add a barbed fitting that i will silicone to the box and attach a hose that i will run down thru th body via a drill bit about3/8 th inch dia in the firewall( sheet metal in front of your feet) so the water can drain. I will also add a couple of holes below the carpeting to drain at least some of the water if it gets in there
  
to get at the condensor box looks like taking the entire dash out. I got to the heater core and can remove it if needed, if i could acess the A/c condensor then i would HOWEVER it looks like to get to it means removing the entire dash. It looks like a job in itself ( failry major thing to do)

I solved the problem of water leaking inside on my 2001 Pontiac Montana by adding a PVC elbow to the short plastic drain sticking straight out through the firewall. A deteriorated seal behind the firewall allows the water to run back the drain spout and inside the vehicle. I inserted a short piece of 5/8 " heater hose in the 3/4" PC elbow to make it fit on the drain spout and added caulking at the back to prevent any water entering the firewall. This was done from under the vehicle. It's tricky but doable with patience. Of course you could rotate the engine forward and have better access to the drain.
