Chevrolet - Silverado :: Only Hot Air Coming Out Of Vents
Apr 21, 2013
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?

So I changed my plugs and wires on my truck a few days ago and now every time I turn my key on a loud electrical noise comes from the engine. I thought it was the front right plug so I changed it. That went great for one day, then the same problem reoccurred. Done this many times never encountered such a problem. It will run obviously weaker than previously. 2000 Chevy Silverado5.3l vortec 4x4136,000 miles....

1991 Chevy 1500 pickup truck. The heater is ALWAYS on, no matter what I do. I suspect that some sort of mechanical controller or vent shut off device/air mixer is malfunctioning because I don't think the heat is actually coming from the heater core, I think it's just engine heat.
I pulled the fuse on the heater which turned off the blower and controls, but the heat is still coming out the vents, especially at highway speeds. So this leads me to believe that exterior air is pulling engine heat into the cab.
I don't know how I would even begin to fix this. I need a starting point. Where would I look for the vent or flap or whatever that mixes the cool air with the hot air? The AC hasn't worked since I bought the truck about 18 months ago.

2004 Chevrolet Silverado 1500 4WD.... Rear brakes make strange winding sound when coming to a full stop, noise only apparent under 5MPH. They have been completely done over. Rear end issue? Changes gears fine, brakes work ok.

I have a 2003 Impala with about 124,000 miles on it. A few weeks back I started to hear what can best be described as a "water gurgling" sound coming from my dashboard area or where the vents are. It happens especially when make a tight turn or something, it only last a couple of seconds and doesn't happen all the time. What am I hearing and what was the cause of this and is there any fixes for it?

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.

My 2009 silverado ltz is haveing heating issues. when you first start truck all work fine. After a couple min the drivers side vents loose heat and blows cold air. the heat on the pass side works fine. then the vent will change to defrost even though the display still shows its on vent. the only way to get it back is to mess with the vent control. then it will last about a min then back to defrost. at this point i just turn it off. I have already replaced the control panel to no avail ...

I have a 98 Silverado with 5.0 liter, 2 wheel drive. When cold it idles at 30 mph plus. When warmed up it runs just fine. This can be very challenging in icy weather. I have changed the temp sensor, cleaned mass air sensor, etc.

I have a 2002 Silverado. I am having problems with it starting. I turn the key to on, and nothing!! A friend told me how to reset or reprogram the key, turn to on 10 minutes 3 times. This does work, but it might be a day before it starts. I don't have a key with a chip in it, it's a regular key. Looking for info on bypassing the whole system.

I have a 1997 Chevrolet Z71 4x4 truck. 350 engine.
This morning I went to start the vehicle and it cranks fine but doesn't turn over. It cranks at a normal speed and then every second or so struggles, and then cranks normally again. About 2 weeks ago I went to start it and the starter didnt engage, it just spun. I released, tried again and it started right up. It did that twice over about two weeks. I figured the starter had gotten too weak, so I replaced.... No change.
The truck has been running quite rough for a little while, and I was doing research to replace the valves and sensors that were recommended (EGR and Idle Air Valves), but the truck seems to have decided that I will do this maintenance now, whatever it is. By running rough, I mean, when it idles, it shakes some. Going down the highway, it runs fine and doesn't miss or anything like that. It is sluggish, but it is a 16 yr old truck with 230000 miles, so it just seemed somewhat normal.
I have checked for spark, and verified that. I can smell fuel when I crank, so I don't think its a fuel problem, although tomorrow I will see if it will fire off starter fluid to verify. I have had the rotor go out before, but it seems when it did that it didn't stagger when I crank.

2000 Silverado 5.3So I recently replaced my head gaskets. And I think I'm finally done working on this truck when I took it for a long drive and it did a little sputter and then backfired. I thought it was nothing since after the backfire it went right back to running perfect. Then again another day it did it again. Sputter. A loss of power and the BANG backfire and it was back to running like new. At first it was very rare. Maybe once every other day. Now its doing it 2-3 times on a normal drive to work. And it will idle rough during one of these spells as well now. When it starts to sputter and lose power I can throw it in neutral and rev it a few times. Once it backfires it's back to running like new. Only codes I'm getting are o2 sensors but I have no cats. Just straight pipes from headers to a turn down exhaust. I was thinking maybe a fuel regulator but I had replaced that just a few months ago. Could it have already gone bad? I changed my fuel filter not long ago and cleaned injectors and rails when replaced head gasket.

My 2001 Chev Silverado 1500, 5.3L, 260,000 K miles may finally be near the end - It has been running great until this week. I live in Portland - weather was down to about 10 deg F a few nights and when it warmed up again the trouble started. After starting cold and driving for about 15 minutes it starts stalling out.
Sometimes it will fire right up again and I'll hardly notice except for a momentary drop to 0 on the tach. Other times I'll have to pull off to the side to the road and restart it. However, 2 times now it would not restart and stay running. It would either fire up but then die within 10 seconds, or it would just crank. Both those times it did restart successfully after 40 minutes had passed total and it drove fine afterwards until I got where I finished my commute (about another 5-10 minutes of driving).
I took it to a mechanic who could see it stall but was not able to duplicate the 40 minutes out of commission thing. His fuel pressure gauge indicated that the pressure was fine during the stall outs. The mechanic ran the computer diagnostics but didn't see anything unusual. He wasn't really sure what the problem was. He recommended replacing the fuel pump and fuel filter anyways - but couldn't say if that would make any difference.
Should I start throwing money into new parts or move on and start looking for a new vehicle?

I have a 1983 Chevrolet C10 Silverado that I am slowly restoring. I recently had to change nylon timing gear and chain. It ran ok but now will only crank but not start. I am getting gas to the carb and I tried a couple of shots of starting fluid. It didn't try to start at all. I pulled some of the plug wires and I am getting spark. The plug wires look good. I am starting to get a little stumped.

The CEL came in on my friend's Chevy Silverado .....so he took it to the dealer for diagnosis/repair. After paying for the diagnosis and repair (supposedly he needed a new gas cap) he was good to go. A few days later the CEL came in. I have a code reader so he asked me to check the CEL code. It's P0442. The same code that the dealer sited. Since we know it isn't the gas cap what are the other most likely suspects? He says the truck runs fine. No drop off in MPG, no misfire, etc.

I have a 03 silverado 1500. I was putting in new speakers for the doors so I took the panels off and unhooked all the connectors.once I hooked it all up again and put it together the window,power mirror,mirror turning signal, and locks won't work for the passenger side. I can't work it with the driver side controls either. i've unhooked the battery and let it sit for an hour to reset the computer but it hasn't made any difference.

When parked and you shift between P to D or R loud engagement of transmission. Thought it was u joints, buddy says both look good/sound good when engaging P D R. Also shifts hard between 1-2-3 intermittently. I did read that it could be the TCC regulator valve?

2012 Chevy Silverado 1500 LT... My brother took my truck off road yesterday by himself and when I left there was a noise on the passenger side. It sounds like slowly tapping an empty barrel, it ranged from a low noise and a little louder. Randomly while driving... Bumps in the road wasn't the problem or turns didn't make it either. I found a thin stick with burrs stuck underneath and took it out but when I left driving again it still made that noise. It might vary by speed but I doubt it I only drove a couple times and that's all I perceived so far. I am wondering if I should be driving it at all now? until I can get it looked at I also called my brother and asked if he hit any bumps or holes real hard but he said no hoping he's not lying to me.
