[DML] Re: A/C cutting out



Does your a/c turn off when running it at either the third of forth click on the fan blower 
speed? If it does, you may need an upgraded relay. If I remember right, these blower relays 
are more narrow that the regular relays and are silver in color. The original relay's amps 
where too low, which made them click off to cool down. When they'd cooled, the blower 
would kick back in. Try switching your fan speed to one or two klicks.. those are on a 
different relay.
