Hello, I have a 94 Lexus es300, and when I recently turned on the climate control to used the defrosters the ac light started to blink and the defrosters stopped working I had to turn it to heat for it to work properly. Smh not a vey good look if it's hot outside. I was just wondering what the problems could be, I was thinking compressor but someone told me it could be as sime as a relay gone bad. Any advice would be good. Thanks in advance
