It gets like 115 here and I had black leather interior so It's so hot in there and with it only blowing on medium sucks. My kids in the back seat burn up.

If high doesnt work and you can turn the fan down 1 position and it works, I would think the problem is in the speed switch itself. If the speed resister failed and took high speed out then all the other speeds would not work, also a speed resister would be a permanent failure not intermittant. I cant see the blower motor being a problem, or the wiring at least not affecting high speed only. You might still check the wiring to the blower motor though because they are known to get hot and melt.
