Hi there! Thank you for using Just Answer. My name is ***** ***** I'd like to try and help. Sorry to hear you are having issues but with my help I am hoping we can figure out a solution to your problem.

First off, could you elaborate some on what the issue is, when and how the issue started? The more complete the information you provide is, the better I'll be able to help you find a quick and accurate resolution. When you are saying its blowing hot, do you mean heater hot or just outside air hot?

First check I would like you to perform is to check all the fuses with a multimeter. Do not do a visual check as this is unreliable. Also, swap relays with same type relays or check relays with relay buddy.
