hi, i bought a 1995 explorer xlt, everthing works great. there is a rocker switch on the left sdie of dash boardand it appears to be factory installed, it has three settings, normal \ off\ low temp. there is no mention of it in the manual. the only thing i notice is that i i select low temp, the lights on the read out on the roof computer dims. as i live in a "colder" climate was wondering if any one knows what this switch is for? vehicle also has a auto start, but the switch on the dash appeards to have been installed at the factory.
thanks
