left vs right vent temperature (a/c)
left vs right vent temperature (a/c)
I've fixed the temperature cable - it was off by 1/4" or so.I've fixed the recirculation servo - the output gear was stripped.Refrigeration pressures look OK, more or less. There may be some non-condensibles in there. The pressure at rest was slightly higher than it should have been on the R-134a T/P chart.With A/C on, Recirc on, select to vents, blower max, windows open (at full load), the high side was near 245 psi, low side was between 40 - 45 psi.forgot to say this before - ambient Fresno air was over 105° that day. Is about 100° today. Ugh.PROBLEM: The dash vents are warmer and warmer toward the passenger side. Left vent #1 was around 60°F, #2 was warmer, #3 was warmer yet, #4 was about 95°F!!!I figure I have to pull the dash and see what's broken or out of place in the duct work, ya?Help! Fresno is getting HOT!D²2004 Vibe AWDPS: (air velocity from vents seems weak to me, blower SOUNDS ok)
Re: left vs right vent temperature (Daddio)
check the filter, might be something in there causing the low wind speeds. as for the duct work, might be something in there. or possibly the vents aren't opening and closing properly depending on where the flow is supposed to be going.
None. Vibe is gone.
Hmm. Is there a diagram somewhere of the air handling system in this car? It looks like the mechanical linkages are all correct. The parts look to be connected right, snapped in place, screws tight. I have not pulled the dash, but you can see an awful lot with a flashlight by pulling the control bezel and by sticking your head way down on the floor. Do I really want to pull the dash apart? I mean, before I've heard of anybody else with warm right vent and cold left vent?
Oh boy, I'm into it now... the upper dash is off, and I'm realizing (please tell me I'm wrong) that the duct work does not come out without removing the big steel crossbar. That's question #1.I can see one of the gates opening and closing, and maybe not quite sealing all the way. It makes no sense that the right side would be warm, based on what I see.#2) Do you think the evaporator have some restriction in part of it?#3) Would a low charge leave half the evap too warm?Really, would any evap imbalance cause the right side to be warm?I'm going to have to put this back together and just wonder for now... Ugh.
Re: (Daddio)
I'm so relieved to be left with NO EXTRA PARTS!!. I'll post some pics later, but here's what I did:The duct work that snaps onto the top of the evap housing wasn't sealing very well. I jammed some shims under the snap latches to tighten the grip. Seemed to work some.I adjusted the selector cable slightly to tighten it up a little.Nothing looked out of whack, really, but I could not see into the evap housing. That's next I guess.
Dual Hot AND Cold Vents... ME TOO ! ! ! !
Daddio, did you FIX IT YET ? ? ? ? ? ? ? I NEED HELP TOO ! ! ! TODAY I tried to refill my 2004 Vibe's freon, only to discover that the pressure is already about 35psi, where I'd expect it to be when full. Then I ready your hot and cold vent thing, and checked mine..I TOO HAVE COLD ON THE LEFT, HOT ON THE RIGHT ! ! ! ! I didn't notice it at first, because I leave the left ones shut, which I suspect causes it to mix hot and cold, and deliver "slightly cold" to the driver, hence why I figured low freon.Did your above steps fix it? Can you explain how to fix this to me ? ? ? Any PICTURES would be GREATLY appreciated!

Re: (FishTail)
Sorry, been out of touch for a while. No it did not fix the problem. In fact, if I close all the vents but the right vent, I thought it would force the cold air that-a-way. Nope. Still hot air coming out of there. Weird.Great diagrams!Oh, I'm looking for my camera...
Re: (Daddio)
Glad it helped. You may want to check some of the things I listed in these two posts.... may give you more ideas too. http://forums.genvibe.com/zerothread?id=41684 http://forums.genvibe.com/zerothread?id=41683...I know think my REAL problem is not "hot air on the right" but actually "air overall is not cold". The "hot air on the right" I'm starting to think has always been there, but is simply not noticeable when the air is coming out at 50 degrees or colder.Pleas DO share your pics, and findings, on any of these threads... where ever most relevant/appropriate to future users.
Re:
A friend of mine runs an auto repair shop here in town. He gave me a break on an evacuate & recharge. I'm not sure how long he pulled a vacuum, and I didn't hear if he found any leaks. I did hear that he got my left vent blowing at under 40°F and the right vent at about 45°. He thinks there must be some loose duct work under there to cause the gradient.I hate not knowing why...
Re: (Daddio)
DADDIO: does that mean YOUR entire problem, was simply a dirty cabin air filter?MY SOLUTION: I ended up taking it to 2 shops to fix my problem. The first shop charge me $70 to pump it with dye. They said I had a pair of BIG leaks, and a few smaller ones. Assuming they were honest, THAT MEANS THE DO-IT-YOURSELF GAUGES THAT SAID MY FREON WAS FILLED, WERE WRONG! And all this time my system was empty. That first shop wanted $500 to $1000 to fix "everything", which meant they would replace major components. The second shop I went to, said they could "repair" the defective schrader valves (replace few small parts in them) vs replace the full hi and low lines. They also placed a gasket in another leaky spot, and said there WERE NO OTHER leaks. This second shop, cost me only $200. Now, I'm cold and happy.
Fish, that's entirely possible. Trouble is now it's even worse. I wasn't going to pay $25 for the part yesterday, and today the places on the way home didn't have the $14 or $11 ones in stock, sooo I was just running it without a filter. Airflow was fantastic! But temperatures were back to barely cool. And there was a funny noise from the compressor or clutch. while running errands today. Starting the last leg home, the car had trouble even running for a bit. I quickly determined the compressor had seized. I now wonder about possible over-oiling by folks putting in too many of those 134+oil cans. Or when I had it evacuated and recharged, did the evac pull all the oil out leaving the compressor deadly dry? I don't think so. How much does a compressor cost?
Re: (Daddio)
during recharge , he should mix the refrigerant with a small percentage of oil or else it might damage the compressor and the seals
