My heater will blow hot when the fan speed is set to the lower two speeds but when I put the fan on the higher speeds the heat starts to turn cold almost right away, but when I put it back to low it gets hot again. It doesn't matter whether the button for the recirculate mode is on or off, defrost or whatever. WWhat is the cause of this?This is on a 2005 Chevrolet Silverado 2500 HD truck.
View 1 RepliesChevrolet - Equinox :: 2005 - Oil Residue In Coolant Pressure Tank
My wife has a 2005 Equinox and we discovered an oil residue in the coolant pressure tank. I wanted to diagnose the problem myself and hopefully rule out a blown head gasket. I flushed the system and replaced the hoses that had began to break down. I dove the car for a while and let it sit overnight. Sure enough the oil came back. This time it was blackish put couldn't really tell. The 3400 engine in the Equinox has no pressure on the top of the engine while running so transmission cooler must be the culprit. I ordered a new radiator and the broke one sat in the shop over the weekend and while it was there it drained. The milky fluid leaked out and separated from the coolant. I then knew it was trans fluid because it was red after separating. Changed the radiator and the problem is fixed. One thing I did learn is head gasket doesn't mean engine killer.
View 6 RepliesChevrolet - Tahoe :: 2005 - Coolant Temp Gauge Went All The Way Down To Nothing - Losing Pressure?
We have a 2005 Chevy Tahoe. Been running great. Has 140,000 miles on it 80% open road. Couple of weeks ago was highway driving and noticed the coolant temp gauge went all the way down to nothing, and then back up to normal (middle of the dial) This happened 5-6 times and each time as the temp rose back to normal, the transmission would lurch.
I took it to a mechanic who could not figure out what was wrong, but acknowledged it was running terribly. He said that was what he would try before going to a dealer. I agreed and the car instantly seemed to be running perfectly. Now a couple of weeks later, the coolant temp gauge is dropping again. It is not going all the way to nothing, and the transmission is not lurching. It goes down from half to a quarter and then back again. So something still seems to be wrong. Otherwise all seems to be well.
Chevrolet - 2500 :: 2005 - Fading Brake Pedal With Constant Pressure
MY 2005 chevy silverado 2500 developed brake problems. The power steering pump, master cylinder, and Hydro static something or other has bee replaced.Now the pedal fades with constant pressure. The shop tells me this is ok but today at at a downward sloping boat ramp with the pedal at the floor, it was very scary.Before the parts were replaced this problem did not exist.

View 8 RepliesSilverado :: Getting Code P0523 - Engine Oil Pressure Sensor?
When my check engine light came on I hooked up the tool to see what code I would get. This is the code I'm getting which indicates a problem with the engine oil pressure sensor/switch circuit high voltage.
Question 1: is this a simple fix and about how much do you think this would cost at a Jiffy Lube or Walmart type place?I'm also concerned because the MIL is no longer on. I'm wondering if I could have cleared it off using the tool. This morning the engine light was no longer lit and my oil pressure guage is reading no pressure at all now.
Question 2: could it be possible to have no pressure? or like the code indicates it's just a matter of the sensor not reading the pressure?
Question 3: is it safe to operate the vehicle? I'm not going to have any money in my budget for at least another month.
Chevrolet - Silverado :: When Cold It Idles At 30 Mph Plus

View 4 RepliesChevrolet - Silverado :: Only Hot Air Coming Out Of Vents
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 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.
View 3 RepliesSilverado :: 1997 Chevrolet Z71 4x4 Truck Will Not Turn Over
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.
Chevrolet - Silverado :: Random Sputter And Backfire
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.
View 4 RepliesChevrolet - Silverado :: 2001 - Stalls While Driving
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?
Chevrolet - Silverado :: 1983 Cranks But Won't Start
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.
