So today I went out and all was working great, both sides were blowing hot air as before. but 10 minutes later when I restarted the X, she started blowing lukewarm air again. I touched all hoses and they feel hot. Located what seems to be heater control valve and all of the hoses are hot. What can be the problem ?
