2 weeks ago i was driving home from work with my ac on full blast and once i got hoem i noticed the temperature was touching the H. i found that weird cause that never happend b4. then yesterday and today the same thing happend. this time i popped the hood and noticed my ac fan was running but not my radiator fan. so i got a new thermostat changed it and let the car run for like 40 minutes. No fan. so then i went to the dealer thinking it was my cooling fan relay. i changed that and let it run for another 30 minutes and still no fan. so i went back to the dealer and told them that the fan still wasnt coming on, and i noticed that the bottom radiator hose was still cold while the top hose was really hot. HE sold me a thermostat switch. According to him, that was supposed to tell the fan when to come on. My fan still doesnt come on. I ran wires to the battery to see if the fan was workign at all and they worked. Ive run out of ideas at what could be wrong. could someone please give me some advice?
