SOURCE: 2003 Chevy Silverado AC blower only works on 5

Hi some of them are a pain ,but if your paitient you'll get it ,they are normally held in by 3 7/32nd bolts just remove the connector and remove the screws and it will come out ,if the floor insulation under your carpet gets in the way I usually carfully take a utility knife and cut out a small square to allow more room to pull it down and out ,depending on the placement of the resistor.

SOURCE: have a 2003 chevy silverado 5 speed can not find

The manuals have 2 plugs, one on top and one on bottom but both on the side. They are usually located on the pasanger side of the body of the trany. Its about a 3/4" to a 1" plug with a slot to place your 1/4" or 1/2" breaker bar in. Verys in size. Bottom drains, top to fill and check with your finger for fluid by just reaching it in. Should come close to poring out the top whole. Automatics drain by removing the pan and fill by poring through the trany dip stick tube. The automatic transmisson dip stick tube shoud be close to the fire wall.

Chevy truck 2003v6 4.3engine starts but then dies

Check fuel presure! Check idle air Controll sylinoid! Or iac and check the crank sensor! Would be better to scan the computer first! This would give you a defined list to deal with! I think that it's a scam that we have cars that can almost drive them selves, but won't tell you what's wrong when a sensor goes?? Good luck!

Correct fuel pressure? EGR stuck open? IAC dirty/stuck? Throttle blade hanging open preventing IAC from working? Yune up issues?

2003 chevy 4.8L truck wont start unless you give it gas any ideas

it sounds like the device used to control the idle speed is the problem. This is the IAC, idle air control valve. check the electrical plug going to the valve for security. The valve can be removed and cleaned with spray carb cleaner. Clean the throttle bore and plate as well. check for broken or disconnected vacuum lines. Lastly a stuck or clogged PVC or EGR valve may cause similar problems.

You may need to replace the IAC.

go to web site. they will have a tutorial on how to test and replace IAC.

The motor behind the gauge is wearing out, very common on silverado instrument clusters for this to happen.

I can rebuild the gauge so it doesn't happen again, check my site out here
