my 88 honda is great, 126k got for 1500.00, driving it home, a/c was working fine, turned it off to open sunroof, got a little warm , so i turn the a/c back on and nothing, no lights behind the vent control, no light on the a/c button, and now air only comes from the dash vents no matter which button i push ie heat/ high low and such, i have the haynes manual but cant find anything in it about this problem, would love some help, thanks for your time
