C/K :: 1997 Silverado - AC Works For A Short Time Then Stops Blowing Through Vents
Mar 6, 2013
The ac on my 97 chevy k1500 siverado works for about an hour then for no reason the air stops blowing thru the dash vents. The motor continues to run but will not blow thru the vents. At the same time my blower motor will slow down to the lower speed position even when I have it on high. But, if I shout off the ac for a view moments the air will start to come back up to speed and will begin to blow thru the dash vents again. I have replace all the blend doors excep the one for the cab recirculation. Replace the motor relay swith, the motor thermostat, and the dash mounted control module. The heater system seems to work fine.

I just had a bunch of work done on the engine of my 96 f250 7.5 v8 460 and now whenever I'm going up hill, my air conditioner stops blowing from the vents and after I get back of a level ground it starts blowing again. What it could be?

I did a 9 hour drive last week and partway thru the trip the AC stops blowing out of the vents. No combination of punching buttons on the AC system solved the problem, although manually increasing the fan speed caused something behind the glove box to make a LOUD sound of rushing air (still nothing out of vents though). Finally I turned off the system completely for over an hour and then it magically started working again. I assume something in the system froze and had to thaw out. The exterior temp was low (mid-60s) but it was raining and the AC was keeping the windows un-fogged.

I have a 1995 Chevy C1500 Silverado. The blower and heater work great when I start driving. After about 20 minutes of driving on high blower speed, the strength of air blowing out reduces drastically and eventually no air is blowing out of the vents. I can still hear that the blower is blowing air, but there is no air coming out of the vent. The Midas repair shop I frequent couldn't reproduce the issue on their short test drive (of course). They told me to bring it back to them whenever the problem occurs. I haven't had the opportunity because by the time I get out of work, they are closed and I am freezing to death every morning.

2014 Elantra GT SE tech package. This issue is intermittent so I am reluctant to take it to the dealer as they will just say there is nothing wrong if they cannot replicate the issue.
The problem I have is the ventilation inside the car stops blowing air randomly. I could be driving for 1/2 hour, 1 hour, 3 hours, and all of the sudden the amount of air blowing out of the vents drops down to almost nothing. I can still hear the fan blowing away at what sounds like full power, but air is just barely trickling out of the vents. Really sucks on hot days! This is going to be a bigger issue once winter comes.

I've got a 1995 Buick LeSabre that has a curious problem with the air conditioner. The AC blows good and cold, but when I accelerate the air stops blowing from the vents. I can still hear the fan running, so it's like the air is being redirected somewhere. Now, once I get up to speed after accelerating, if I let off the accelerator for a second, the AC resumes blowing normally.

4.0 v6 A/c works great at first. Then after a while stops blowing out the center dash vents. What to check? Still blows cold out the vents by each front door...

I have got the most aggravating electrical gremlin possible. For over a year now, the truck intermittently just dies. Mostly it happens about 2-3 mins after start (every couple weeks or so), then takes a couple of key offs, then back ons to restart. But it does restart and then runs fine for a time.... 2 weeks ago I was rollin' down the road and hit a pothole, and whammo, she died, and wouldn't restart. I thought, "great it was the intertia cut-off going bad." I had it towed to the shop where they did some diagnosis and told me it threw a PO231 code.
The tech then said he was doing the diagnostic manual directed test, and swapped out the fuel pump relay, and it started right up. New relay, out the door. A few days later on the way to work about 2 - 3 minutes after start, she dies again. I hang my head, say a curse word, and key it a couple times, and it starts back up and runs fine. Presently speaking she's back at the shop, but the owner, who's a straight up dude was loath to take her back, because it was running fine at the time.... I've got to figure this thing out before I drive it off a cliff.
Truck -- 2001 7700 XLT 5.4L 88K miles
Symptoms -- Random interval engine stops with short delay to restart, 1 hard bump engine stop with no restart. PO231 code (after the hard bump no restart). Didn't check it previously (wasn't aware there were "soft" codes).
Troubleshooting to date -- 1 new fuel pump, 1 new fuel pump relay.
Only things left are the inertia cut-off switch (which apparently don't go bad that often), and the wiring itself/connections to the different components....

The AC works, but just not well enough on a really hot day. On a day in the 90s I have to put it on Max AC and even then it does not cool down for a while and the air out of the vents is not ice cold.
So, it works, but I cannot tell if there is something wrong or not. I recently put in a can of AC Pro and it did not change anything.

My A/C is blowing cold but only thru the defrost vents. First it was blowing normally from the dash but during acceleration or under load, the a/c would randomly blow from any vent, from the floor, dash, defrost. Now that stopped and it only blows from the defrost vents above the dash-board.
1997 F-150 XLT, 4.2 Liter, V6, manual transmission.

2001 F150 5.4 4wd - AC not working but when I turn the temperature dial to the blue side and turn on the fan, super hot air comes out of the vents or wherever I direct the fan to blow (Floor, defrost, etc) I know it shouldn't blow ice cold especially since my AC doesn't work but.....shouldn't I feel a temp change coming from the vents when I move temp dial from the red area to the blue? It's max heat wherever I have it set.

1998 F150 XLT 4.6l automatic,,,
Drove the truck on a trip the other day, about 650 miles with a loaded 5x8 trailer in tow. A/C started acting weird. When the truck was on level ground, or going down hill, the A/C was fine. Cold air coming out the correct dash vents. As soon as I started up hill, or put the truck under strain of acceleration, the A/C would stop blowing out the dash vents and would start coming out the floor or defrost vents, or just not come out anywhere.
When I turned the A/C off and just used the vent setting, it would do the same thing with the fresh air. I guessing this has something to do with my vacuum lines, somewhere. What I should be looking for and where?

My 97 e350 club wagon is doing something weird. Front AC wont go to Max Air, the blend door wont function. Can hear vacuum trying to work. Rear Unit is on Heat even though Front is on AC and blows hot air out the rear floor vents. Hit some high water going too fast about a year ago. Next day, this started happening. Rigged up blend door so air flows through vents.

My 2002 f150 blows the overdrive fuse (#29) every time the overdrive tries to engage. Could it be the overdrive switch? Where is that switch? Could it be a speed sensor? Truck has an automatic transmission and a 5.4 engine.

I just took possession of a 2014 Passat TDI Highlight (Canadian).
The rear spoiler comes standard and installed at the factory. I washed my car yesterday and I noticed that the clearcoat on the top of the trunk stops short about 1 or 2 mm from the edge of the spoiler. Now, that seems a bit odd to me as I would think they would paint and finish the car then add the spoiler after.

I've recently purchased a 2007 Prius and I just noticed few days go that A/C blows warm air (weather was fair when I bought it and I can't remember if it really worked or not then) and middle vents do not blow any air. I'm not sure if two problems are connected but I do want to get both fixed without spending $$$ at the dealership. Where can I start?

I get a musty odor from my vents from time to time. It usually happens on days when it is damp out and often on startup but sometimes it happens later in the trip. Its quite strong, unpleasant, and terrible for allergies.
I read something about this a long time ago but cannot find the posts. Found a TSB summary on VW's site but Dealer pulled it and says its for Passat. Thinking its something in the A/C or ventilation system.

I have a 1999 C2500 Chevy Silverado extended cab. On some slow speed stops the ABS kicks in and makes it hard to come to a full stop scary. There are no leaks in the system. The ABS light has come on, on the dash off and on. I thought I saw a post that you can shut off the ABS system not the real fix but safer until I can figure it out.

I have a 2004 Chevy Silverado (4x4 Extended Cab 5.3 L Engine) that only seems to "heat" the interior of the vehicle through the floor and dash vents. Hot air comes out of the vents no matter what I do ( I can direct this flow of hot air to the floor, dash, or both) . Even whe I use the A/C at the coldest selection it does not change the fact that HOT air is coming out of the vents. I am guessing that a door of some sort is "stuck" so that only engine heat is coming into the cab. Not sure if that is possible but just a thought. Whats going on?

I just got my Prius v for few days. I noticed that I only saw the battery bar fully charged once and for a very short time. Also, when I idle my car for a period, the battery would drop to three to two bars. Is it normal or there is a problem to my battery? I got 49500 miles on it,

My car is 6 cylinder 2000 Oldsmobile Intrigue. It won't start after a short time of being off. It has to be more than 2 hours off before it starts up. What is wrong?
