A/ C was working fine,then ,nothing,started blowing all hot air. I dont know much about A/C so <i got a recharge can and tried to charge it. It wont even take any of it. Compressor doesn't come on,and now the control panel read out is all lit up,showing -188,E8 ,it also shows fan on full,defrost,heat,etc... wtf ? Anything off the top of your head you can think of ? I am asking around about trusted shops in the area,just scared to pay a fortune . Thanks for any help.
