I guess the aircon deserves a separate thread, so here goes...

Do you turn off the aircon first when switching off the engine? Because when you don't, the next time you switch on the engine, the aircon turns on automatically. I don't know if it has bad effects. Personaly i do turn off the aircon before switching off the engine. A couple of times though, i may have forgot to kill the aircon... buti na lang walang masamang effect pa. Curious lang ako what bad effects this causes when done regularly.
