the code is p0442 what dose that mean and what part do i need
Posted by anjelits73 on
this is a small leak in the evaporative emission control system.Most common cause is a loose or faulty gas cap but not always, Sometimes the check valve in the gas cap doesn't seat properly allowing the gas tank pressure to bleed down. The EVAP system needs to see a positive pressure in the tank.

2004 trailblazer fuse box picture
Posted by klbowman71... on
problem with this is what is what or no pic on it?
Posted on Aug 17, 2010
I have a 2004 Chevy Trailblazer. My son ran the battery down and my wife had to get it jumped to get it started. I found out later that they initially tried to hook the battery cables to the red and black cables leading into the fuse box. After getting the car jumped, the car has the following electrical problems:
1. Radio will not work
2. Electric locks will not work
3. Windows will not work
4. Interior lights do not work
5. Cigarette lighter does not work
6. A/c does not work. The blower does work
7. Dash lights do not work
I checked the fuses that you can visually inspect in both places and did not see any blown fuses. Since this happened after attempting to jump the car in the wrong place, I am assuming that this is the cause of the problem.

Hey everyone with this problem! Theres a fuse under the hood in the front of the fuse box. Its black and its not in the bow itself but under the cover though! two nuts hold it in place where your cable line comes in from the battery. The fuse costs $15.00 avg. most anyplace! Easy to change and everything will work inside your vehicle! Without it the vehicle will start and run but you will have no functions on the interior, or dash!

My SES light came on yesterday under what I would consider to be normal driving with no noticeable problems (at least to my untrained eye and ear)... I ran the OnStar diagnostics, and they told me they received signals indicating an error with ether transmission or power train.
Today, I called the Chevy dealer, and they want $100 just to run a diagnostics on it. Then the repair costs would depend on what they find.
Is there anything I can do prior to bringing it to the dealer to check things out on my own?

1. Turn key to the "on" position but don't start car
2. Pull the PCM BAT and PCM IGN fuses in engine compartment
3. Wait approximately 5 minutes
4. Turn ignition off
5. Replace fuses
6. Start the car and the make sure the light has went off.
then check to see if your gas cap is on right. If this light comes on again then it is time for the dealer. If you can't find them fuses then just disconnect the battery for five minutes reconnect the battery and when you start the truck the light should be out. just let it idle for 2 minutes with no heater or radio on. and you set. I hope this helps you.

Where is the cruise control fuse in a 2004 chevy trailblazer?
Posted by ramblerma8... on
Gotta tell you, this question had me a little confused. Below are 2 wiring diagrams for you. One is for the cruise control circuit and the other is for the air conditioning circuit. The reason I gave you those is because it seems according to the wiring diagram in the cruise control that the fuse for the cruise control goes to the HVAC (air conditioning). According to the wiring diagram for the A/C yes that fuse also controls the ignition power for the A/C controller. In any case the fuse that would cover the cruise control is the number 30 fuse in the fuse panel located under the hood of the vehicle. Below is a picture of the location of the fuse panel and also fuse layout diagrams for the 6 cylinder and 8 cylinder engine vehicles as they have different layouts depending on the engine size. I hope this helps you and good luck.

What does this mean and Coolant Thermostat
2004 Chevy Trailblazer
Along with all my mph and rpm is all going crazy what does this all mean
Posted by selelatin2... on
P0410 secondary air injection system malfunction. I've dealt with this problem myself. It's either the air pump which is located under the driver's side door on the frame, or it's the valve on the engine that is sticking.
The air pumps are notorious for "freezing up" in cold climates due to water sitting in the pump and freezing and then breaking the impeller from the shaft in the pump. This is what happened with mine.
Remove your pump and test it. If it spins and blows air,then it's fine. Then check your valve on the engine. If that opens (which they like to get corroded with exhaust gasses and stick) Then that will be ok. If not, you'll have a pretty good idea what is going on.
I wnt ahead and replaced both the pump and valve, which were both crappy.
GM also has a check valve that you can install to prevent water from entering the pump. I just drilled a small hole in the bottom of mine to "drain" the water.

Had front brakes and rotors replaced and the light comes on sporadically. What do I need to do to reset system?
Posted by Phyllis... on
It doesn't need a reset, a mechanic needs to scan for the fault code that is setting the warning light. It could be a poor or no connection at the wheel speed sensor or a problem with the ABS.

When I turn on the air conditioner my trailblazer dies. First we thought it was the battery. It started resetting itself every time it set too long. The clock would reset. Then it would start, but hesitate. Then final it wouldn't start at all. Then we had to jump it. Got a new battery. Now it starts. But when you turn on the air it dies. As long as you don't run the air it is fine. If you turn on the air while sitting or idling it dies. If you get the speed up or are driving it is ok, but if you are stoped at a light or just sitting it will die or if you are slowing down to turn with the air on it will die.

just check weather all spark plugs are ok, even if one misfires then turning ac on will stop the engine. during motion the ac manages to get the power from other plugs. i hope this solves ur problm.
