Recently when I was running my air conditioner, it just turned off all of a sudden and wouldn't work on any of the settings. A few days later, it started working no problem for a few days. Every few days it kept happening again and I noticed a burning smell when it was on. After working on it this weekend, I replaced the blower motor and that was NOT it (after being told by a shop that it was). My uncle suggested that it could be the resistor but I pulled it out and it looks fine. No burn marks but could it still be bad? Any ideas on what else it might be?
