oh . sorry . trouble codes
do you have a code reader or scanner ?
disregard the actuator part . no the fuse is labelled HVAC/ECAS . it is not the radio fuse
it should be under the hood , yes .
should be labelled fuse number 38
okay . You will need to scan the vehicle . normally on that application the flashing light is indicating Low refrigerant charge . Can you get what is called a " recharge" or " top up " kit ?
does the A/C clutch ( compressor ) ever turn on ?
okay . It indicates that it is low on R134a refrigerant . I would get a top up or recharge kit . Also on the passenger side firewall the big aluminum tank ( accumulator ) has a switch on it . Turn the Engine and A/C on , set to MAX , disconnect that pressure switch and use a paper clip or something to jumper that plug . Does the compressor run , if so leave it jumpered and see if the tank starts to get " cool "
