Car runs hot with a/c on and when stopped at light car will run hot until I start moving again then slowly cools down
how do I locate and change my thermostat on 2004 Chrysler PT Cruiser
Is the cooling fan running?
The problem probably isn't the thermostat, but sounds like your cooling fan isn't working. Especially, as you say, it cools down once air starts moving thru the radiator again at speed. But if you do wind up changing the thermostat, be mindful of the "clocking" marks on the gasket to match up with housing. Otherwise, it will leak for sure.
