sIIooo

Hey guys I have a question. I was driving on the freeway yesterday and I had the AC on when it just stopped blowing cold air, I looked at everything and didn't see anything but then I noticed my temp gauge was showing 4 bars instead of the normal 3 (ap1). It was about 110 deg outside and I have an intercooler on my car (not turbo had to take it off to get smogged) when I turned the AC off the temp went back down to 3 bars, is this normal since it was so hot outside and I have the intercooler which might be blocking more air from getting to the radiator?
