I have noticed every year in the summer weather that while riding in the city with the a/c on, my temp needle stays close to hot. My fan works, I have plenty of coolant. What can I do to fix this, I noticed the same thing on my mom's 96. My wife has a trailblazer and you can park and leave the a/c for a long time and the engine not get hot. I put a tranny cooler on last week while I was having my tranny rebuilt. Is there anything at all, this is frustrating when you cant run your a/c when the temp is above 80degrees outside. We have bad humidity and heat in west TN.
