My whole HVAC system in my 04 Screw Lariat is litteraly blinking. As if someone installed a christmas flasher in the system. Power on or off (particularly distracting at night when dash lights are illuminated). Have checked the owners manual as I am not a true tech but a very proud owner. All indicated fuses appear intact. Not a real diode or relay whiz so if any of you have an idea please let me know. This is the electronic controls model. Seems like a relay problem to me. Blower, clutch, door, lights, display,fan & compressor all come on pause off pause on pause off pause. Really annoying that the June/July swelter season is upon us.
