I have a 2000 Nissan Frontier that is a 4X4 and has the V6 engine. Mileage is 172,000+. For a few years, I have had problems with the AC no longer cooling after I drive 20 or so miles and stop the truck, go in a store and start back up only to find that the AC will not cool after the stop. This seems to happen more when the weather is hot. Only once has it gone out without stopping the car and it was on I40 driving trough Oklahoma in 100+ degree weather. Once it quits cooling, after driving 20 to 30 minutes, it usually starts to cool again. It sometimes speeds up the process if I roll the windows down.Coolant levels are fine.
So…is there a faulty sensor somewhere? What could it be that is the problem?
