i lost max air in my air conditioner. when i put on max air i have three speeds but when i kick it into high it goes off. i'm looking for the high speed blower relay. i couldn't find it under the hood. it's not in the fuse/relay box. i couldn't locate it on the firewall so i went inside the car. i now have the glove box out and most of the trim, still no luck locating this relay. everything works fine until i kick it into high, i replaced the switch so thats why i'm looking for the relay. i'm getting hot under the collar, please help.
