loose or broken battery cable or ground wire is my first guess.

If they are like other Saturn's, it's attached above the glove box. Remove the glove box door, and the screws that attach the plastic box to the dash, then pull it down and towards you, the BCM should be on top. It slides out of its holder.

bleed the brakes again starting at the longest line at the rear and work forward . The indication is still air in the lines.

You have the thermometer looking light [ engine temp], you have the radiator looking light[ low coolant. You have the battery looking light [ battery or alternator, and the check engine light. Also a wrench light [ something else wrong could be a number of things] What light are you referring to?

recheck the wires where put on right and see if it runs better

that is a well now problem I have had it on 2 out of 3 cars and sad to say there is only one fix for it and that is replace the complete sun roof (dealer or scrap yard)

it sounds like you CPS on the back of the engie has failed

Under the drivers dash there is a connection for your hand held computer. It's close to the hood release.

Locate and check the oil pressure sending unit. A trip to Autozone, or Advance or one of those parts houses can give you the location. These things can pump a lot of oil in s short time.

most likely a fuel issue, could be a bad pump... turn the key to the on position and listen for the hum of the pump kicking in, if there is no hum it is most likely you fuel pump needs to be replaced or you have a bad electrical connection to it. If it hums there may be a blockage somewhere in the line. letting a gas tank run under 1/4 tank can burn out a fuel pump, the gas in your tank actually insulates the pump and helps keep it cool.

fuses circuit breaker bad.. window locked in place..switch wore out...

my guess would be the valve cover gasket.......easy way to tell is if there is oil around the edge of the valve cover or in with the spark plugs.........but yes timing chain cover could be it also......and yes that could happen with the serpentine but it would be more scattered around

The security, antitheft, or passlock light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterperates this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle.

may be the heater core , or a clogged up coolant system. Do you ever smell a sweet smell, or hear water gargling after you turn the car off?
