    you can leave it on, but i always recommend turning it off. leaving it on puts unnecessary stress on the motor and all when you crank the truck up.

    I'm pretty sure that the compressor doesnt engauge until the engine is running, therefore, no stress starting. I turn mine off, though. :)

    I don't always make a decision to do turn it off. Sometimes I do. I've found that if I leave the AC on when I turn off my engine, I generally get some mildew smell when I start it back up. I've heard that the condensation in the system has a tendency to form mildew.

    I try to turn the AC off a minute or two before I turn the truck off, Usually when I turn into the subdivision I will turn it off and let the cold air out of the ducts so mildew does not form or at least help it not to form.

    I voted yes but honestly mine is rarely on & when I need to defrost have found the first setting (defrost & feet) works the best for me. Never thought about the stress on the engine.

    I can't really agree that the A/C will put stress on the engine when starting. With 236 HP I don't believe that would be an issue. As far as hurting anything, I had my last vehicle 10 years (98 Chevy Conversion Van) and never turned the A/C off and never had a problem.:)

    Triangle dude:

    Regarding the mildew smell. There should be a drain for your condensor in the firewall on the motor side. make sure it isn't clogged with something. The water should be able to drain freely and you shouldnt be getting the mildew smell.

    I went through this on my beater VW a while ago, the hole was clogged with shit, after I unclogged it the smell went away. Stick a coat hanger or something in there.

    thanks. I'll check it out. I've heard that it had something to do with the design of the AC. They started putting the fins really tightly in there to increase efficiency, but that just holds the moisture in there now.

    I have mildew problems and have read plenty about it on other boards. In the hot/humid climate here, many cars (my taco included) smell like dirty diapers if you run the a-c and let them cook a couple of days.

    The manufacturers generally recommend that you run the system with compressor off a few minutes before shut-down, to dry the evaporator coil. There is no way to flash this into control system, as the ECU has no idea when you are going to shut-down.

    The air conditioning condenser engages after the engine starts. It does not load the starter.

    I go one step further as well and turn it off when I'm about a half mile from home. Gives the condensation time to drip off so I don't have a puddle on my garage floor. :) I've heard that helps the compressor as well if it's frozen with ice.
