AC not cooling. I noticed that the AC/cooling fan doesnt kick into high speed after I put the AC on. I pulled the relay in the fusebox under the hood labeled FAN NO 1 and plugged it back in. The fan kicked into high speed for about a min then turned off on its own. I pulled the relay and waited, for about another min then put it back in. Fan kicked in again then turned off just as before. I did it once more with the same results. I think the fan relay may be bad overheating itself thats why when i pulled it, the relay cooled off and worked again until it overheated again. What do you guys think ? I have a temp gage that I stuck inside the AC vents and watched the temp drop until the high speed on the fan stopped, so i found why my AC isnt cooling. Compressor is engageing, charge is fine and no leaks. I replaced a leaking valve core on the suction side thinking that was the problem initially, and thats when I noticed the fan wasnt kicking into the higher speed when AC was on.
Im thinking either the fan relay OR maybe my cooling fan is bad therefore overheating the relay. As a side note I there was a day when I heard a HIGH pitched sound comming from under the hood, pulled over and couldnt find anything. I didnt want to cause anymore damage so i turned the car off, turned it back on and the sound was gone. In retrospect im starting to think the fan was overspinning ( it was LOUD ). I did notice that the air AC didnt feel as cool shortly after but the temps were MUCH cooler at the time, so it was harder to notice. Now its much warmer. Any suggestions ?
