My hhr will not turn off, where is the battery so i can disconnect it

hi,
sounds like you have a security problem have it checked by a shop. you could disconnect the battery and see if that works.

faulty relay or some wiring issue
..needs fixing will drain the battery flat

The first place to start would be with the new ignition switch.What you are saying sounds like a defective switch.

There are guides in the ignition unit that might have fallen out of position, u need a specialist who does this to fix it for u, pliz dont force the key out. Its a few minutes job.

yes. you can disconnect either the neg or pos cable from the battery. failure to do so can result in a surge hitting the ECM...and frying it. as a rule of thumb...anytime you work on anything under the hood,except for oil canges...disconnect the battery. safety is first!!!

the alternator as got one way diodes in it. charge up the battery and disconnect the negative battery terminal for a few hours etc, put the lead back on , if it starts you need a new alternator, the alternator will of been discharging to earth when not running, good luck.

remove the forward portion of the left front of the wheel house liner, ( the plastic peice inside the fender behind the drivers wheel ). disconnect the electrical connector and turn the headlamp holder 1/4 turn counter clockwise and remove . reverse procedure to replace.

I had this problem with my 2007 HHR. I drove away with the service engine and the service traction light on. The car was stuttering through the gears. I took it back and they checked it. They disconnect some wires while they change the oil and one was loose. The service engine turned off but the service traction stayed on. We disconnected the battery for 3 minutes and it fixed the problem. Some of those other guys spent up to 300 dollars to fix the problem. Hope it works out for you.

Open the back hatch of your Chevrolet HHR.2

Lift up the floor mat on the bottom of the trunk. You will see your spare tire, jack and OnStar unit. Unscrew the top of the OnStar unit, using a Phillips screwdriver.

Remove the lid from the top of the OnStar unit box; you will see three white plastic cables running from the OnStar box to your vehicle.

Unplug the three cables from the OnStar unit to disconnect them.

To change the air Filter on an HHR:

It will take some time, so be patient.

1. Disconnect the air intake hose to the filter box. It is at the left rear of the box as you look at it from the front of the car.

2. Disconnect the MAP sensor wiring.

3. Disconnect the coupling to the engine intake.

4. The filter box is help in place by two ball and socket type retainers located on the back corners. Grasp the box and lift up firmly to lift it free,

5. Turn the assembly upside down. There are seven torx screws securing the cover of the filter. Remove them and replace the filter.

6. Reverse the process to re-install the filter box.
