Well ,the A/C blows very cold it should all under hood components replaced everything changed over to 134a , this is a 93 the HVAC controller did its own thing , could adjust temp up down fan same, sometimes the fan would act like in was in the low mode ,push an air flow button it would do what it wanted to do ?? or nothing ,so took it apart cleaned it (YOUTUBE) video reinstalled removed the batt. cables (BOTH ) left it for 3-4 hrs. reinstalled the cables DA DA works like new ??The cleaning and the Batt. reset ?? I was looking at the blend door fan motor and on and on and or rebuilt controller, the fan never blew this hard and the input bam right now changes, I don't get it, I was about ready to sell this 93 over the blend door deal .. I was like blend door HELL NO .. It all works ..
