Just leave the headlight switch in the on position to have them on all the time, and turn the switch to the off position to turn them off. When you exit the car with the headlights on and engine off, hit the lock button on your remote keyless fob twice to turn off the lights. > >> I'd put a darn thermostat in for the AC compressor >>> so we dont have to do that by hand.

I think making decisions for me is stupid and rude. I wish the designers in Japan would stop it. It's like when the fast food places dump a whole salt shaker on my lunch, it's just rude, and in that case dangerous. -- - Jane Galt Looks like they have Tea Party stickers & shirts for August 28th http://www.cafepress.com/A_REVOLUTIONARY

I thought maybe the heat would be fighting the AC when it was 0 degrees outside. > Besides, you can still run the tempearture control up to hot and get out > hot air. I'm not sure. When the temp gets too cold outside, home and car heaters just arent designed for it.Just like it's hard for AC to keep up when the temp hits 110, it's hard for heating to keep up when it hits 0. They just dont design the systems for those extremes. -- - Jane Galt Looks like they have Tea Party stickers & shirts for August 28th http://www.cafepress.com/A_REVOLUTIONARY

I wonder if this way of thinking comes from the socialist "cradle to grave" mentality, where they think that people are too stupid or incompetent to make their own decisions, so everything has to be decided for them? -- - Jane Galt Looks like they have Tea Party stickers & shirts for August 28th http://www.cafepress.com/A_REVOLUTIONARY |
