I have a 04 gtp For the last week we been having higher then normal weather in chicago and i noticed my temperature gauge been running real high not far from red like when it sits running for about 15 min or been driving a while and stopped at a light i've noticed the cooling fans are not running i turn on my ac the fans turn on and temp gauge tend to stay around normal all relays seem to be fine i also checked it with a tech 2 and commanded them on and they came on fine i actually had my lim gaskets changed last month and my water pump and t stat changed a month prior to that if anyone has any input on this issue its greatly appreciated
