Newbe in need of some help climate not working
 

Hi guys am new to the club i have lexus ls400 gen2 2000 model i cant figure out this issue in need of some help please

i have no climate control working its fozen on a/c mode on screen with a weird flashing demister button on too. Nothing is working not even a/c even though its button selected. Its the touch screen stereo model with sat nav, everything on the unit works radio sat nav.. But climate control, once u push climate button to go to climate screen theres no fan ,no heat, no touch screen responding on climate screen, but on every other screen functions everything works ie sat nav radio so on. I checked all fuses and found the 7.5 a/c fuse keeps blowing under steering wheel changed it blows again, switched relays under bonnet no change, i uplugged a/c plug on a/c pump no change still blows, i toke ecu out and fuse box to check any leaks ie caps or water ingress nothing . I got car plugged in on diagnostics showed no faults but not reading a/c unit as think cause fuse is blown. Please can someone help cant drive my car as windows fog up and its super cold .. Many thanks

Though many models are similar, posting the year and model would be a little helpful. FWIW - perhaps a trip to your Service Dept is in order?
