2007 Saturn ION-2 Quad Coupe - Answered Questions & Fixed issues

Hello, Did you have a specific engine code requiring replacement of the Cam Position Sensor? Did you recently replace the thermostat or run low on coolant or have some other cooling system work done? The temperature sensor can be bad, or simply have a loose wire connection. Check those. There can be air in the coolant system as well. Finally, the thermostat could be sticking and will need to be replaced. These issues have nothing to do with the Air Conditioner. However, the AC will not cool if the car is sitting still unless the condenser fans (electric) are running. Turn on the AC and check to ensure the cooling fans energize. Most of these items you can check yourself, however if not, then have your mechanic or a mechanically inclined family member or friend check them for you. Best regards,

Take it back to the salesman. He knows better than anyone how to do whatever he did for just the one door.

check fuses relays and connections to fan first then test fan[s] for failure if good check and test sensors

When the light is on have it checked for DTC'S - diagnostic trouble codes , do you know what they are ? Ignition system problem , coil's , plug wires if the vehicle has then . The check engine light code is probably for a engine misfire . Check Engine Light On

More likely the transmission - could be the overdrive solenoid is stuck in the engaged position.

Take to your local auto parts, put the scanner on, there not allowed to erase the codes but you can do it with there help.

Why didn't you hook into the entertainment system (radio ) ? The one that turns on when the door opens is controlled by the BCM -body control module .You probably shorted out the transistor in side the BCM . These lamps may be manually turned on by placing the interior lamp switch in the ON position, or by opening a door. • The Dome Lamp • The Rear Compartment Courtesy Lamp • The Rear View Mirror Map Lights The inadvertent power control circuit of the BCM supplies battery positive voltage to the dome lamp and the map lamps. When any door is opened, the door jamb switch contacts close providing a door open input to the BCM. The BCM then provides a ground to the interior lamps. The interior lamps receive a ground at G401 or G403. If the driver inadvertently leaves any interior lamp on the BCM will turn it off after a 20 minute time-out. The courtesy lamps will normally turn off using the theater dimming feature. The BCM provides a pulse width modulated ground to the interior lamps for the theater dimming feature. The courtesy lamps will also turn off immediately if a door lock command is received with all the doors closed, or if the ignition switch is turned to the ON position. -------------------------------------------------------------------------------- Dome Lamps Inoperative ematic Reference: Interior Lights Schematics DEFINITION: Only the dome lamp is inoperative. 1 Did you perform the Diagnostic System Check - Vehicle? YES - Go to Step 2 NO - Go to Diagnostic System Check - Vehicle 2 Place the instrument panel (I/P) dimmer switch in the DOME position. Does the dome lamp illuminate? YES - Go to Testing for Intermittent Conditions and Poor Connections NO - Go to Step 3 3 Disconnect the dome lamp assembly. Probe the courtesy lamp supply voltage circuit with a test lamp that is connected to a good ground. Does the test lamp illuminate? YES - Go to Step 4 NO - Go to Step 6 4 Connect the test lamp between the courtesy lamp supply voltage circuit and the courtesy lamp low control circuit. Does the test lamp illuminate? YES - Go to Step 5 NO - Go to Step 7 5 Inspect for poor connections at the harness connector of the dome lamp assembly. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition? YES - Go to Step 9 NO - Go to Step 8 6 Repair an open, high resistance, or short to ground in the courtesy lamp supply voltage circuit. Refer to Circuit Testing and Wiring Repairs . YES - Did you complete the repair? NO - Go to Step 9 -- 7 Repair an open or high resistance in the courtesy lamp low control circuit. Refer to Circuit Testing and Wiring Repairs . YES - Did you complete the repair? NO - Go to Step 9 -- 8 Replace the dome lamp assembly. Refer to Dome Lamp Replacement . YES - Did you complete the replacement? NO - Go to Step 9 -- 9 Operate the system in order to verify the repair. Did you correct the condition? YES - System OK NO - Go to Step 3

The pressure plate is worn out...usually a transmission shop service...sorry

Check the wire lume that runs from the body to the door inside a rubber bellow. the wires can break from constant moving and I'm not sure what vehicle you have, but this is a defect for a few vehicles out there the wire can be to short in some cases from cost saving manufacturing. It may be necessary to remove the door panel and remove the harness through the wire opening to be able to move the boot far enough to access the broken wire or even just to check it in some cases.
How I like to repair it, is to put a new wire through the entire pivot point and join it inside the door and body where the wire does not move constantly.

Hope this helps

something must be in the way blocking the shifter maybe inside the car something fell into the console or the console was moved or the linkage underneath is bent ? if you can go from 1-2 and have neutral there but can't go further in the shift pattern I suspect what I listed also there could be a broken bushing in the linkage get under it after safely jacking up and put it on stands and inspect all linkage parts for missing or bent parts also look under the console first it easier for an object that's stuck in there ? ( a pen maybe )

check to see if the sensitivity of the system can be adjusted .

A misfire could be a sign of a problem coming up. You might not notice anything major until the cylinder stops working all together. However, other that it sounding terrible, and a loss of power and some shaking effects, it's not terrible. In other words, if it happens, it's time to get it to a shop now, instead of later. Yet, it all depends on why it's misfiring. If there is coolant leaking into the engine cylinder, it's a much larger problem. I would suggest taking it to another shop for a second opinion. Sometimes it's just a simple fix.

misfires can be from the ignition circuit ( coil/s HT leads -plugs) and it can also be from injectors (low fuel pressure -faulty injectors - leaking injector washers --wiring to injectors).

There is a relay under the hood in the fuse box. Check that and the fuses and if they are ok, it is the BCM and those are not cheap.

does this happen when snow is sucked into the vents or does it happen all the time. If it happens all the time it could be a leaking heater core. if the windsheld has a film on it and smells sweet like anti freeze you have a leak in the heating system

Stop by an Auto Zone they will hook up to it for free and tell you the code that is causing the C.E.L. but yes a loose gas cap could cause a CEL to come on.

must be an internal leak. maybe it's in the car somewhere. see a mechanic ASAP !

It would be the switch inside the linkage or the switch on the transmission that causes this or water or corrosion on the connector. I think it uses the signal from the transmission range selector switch on the transmission to trigger the locks. Have it checked out before you replace any parts as this is only an educated guess. The switch is also called the neutral safety switch.

the gas smell is from all the gas into the clylinders when it dont start,,,normal,,,,,,the no start issue is from the electrical ignition switch goes bad when it gets cold out and doesnt let the car start,,you need a new ignition switch like $40 and reprogram it to the car,i would take it to the dealer,asap because right now you are lucky that it does eventually start,one day it will not start at all so get this fixed before you get stuck
