Question about 2001 Dodge Caravan
Security system goes off when running with lights turned on
Check your mechanics manual. There is most likely a sequence of times you must turn your vehicle on, then turn the key back one click. you can actually hear the module trying to reprogram itself. If a vandal was at fault and damaged anything, you may have to take it to a mechanic. My daughters Chevy Venture was stolen and destroyed. Little by little we put things back in order..glass/modules/ignition etc. I was not able to reset the system, and had to take it to a dealer. Still cheaper than a replacement van though. Good Luck! :)

Have you checked the coolant level? What you describe is exactly what happens if the coolant level is low. When stopped at idle, hot coolant is not circulating through the heater core, so no heat. As the engine increases in rpm's when you pull away from the light, the water pump is spinning quicker, and some coolant is making it to the heater core. So check the level, and if it is low, keep an eye on it to see if it drops again. That of course indicates a leak somewhere. Get it fixed, as overheating the engine leads to costly repairs and worse case a new engine. Let me know how you make out with this.
