chassis research

Turns on and runs by itself when the truck is sitting and key is out of the ignition. Sometimes I can go out and turn the key on and it will turn off and then come back on again later. Ideas?

You might want to check the ignition switch down under the dash. I had a problem with the switch a few days ago its a brown wire. are your wipers and turn signals ok?

everything else turns off as it should and works fine. I did have the guages go dead and back on a few times on one occasion but it never happened again.

I'm with you, Junior. My blower motor comes on only after I turn off ignition, and last night ran down car battery. Will check ignition but did I touch the wrong button? 2001 Grand Cherokee, not other issues with electrical that I know of...can anyone help here?

I'll try the ignition, does anyone else have other solutions?

I would call a Ghost Busters, but if that do not work the check the hot/cold switch. Since the blower motor "take" few amp, it should go trough relay. Check this out.
