Hey everyone need help with a problem. Have an 05 TL with NAVI. Was driving one day when suddenly the fan speed went from 3 to full blast.
I also lost my NAVI screen and upper display where the clock and radio stations are displayed.
Up to this point i have done the following.
Replaced NAVI DVD unit in the trunk.
Replaced blower motor resistor
Checked various under dash and under hood fuses.
Still nothing. Fan blowing at full blast. At least the air gets hot once warmed up as its winter here in the east coast.
No rear defroster or navigation or upper display.
Radio and all other electronics in the car work flawlessly.
Any help or insight would be appreciated.
