Hi,
Just brought my first supra and i have a low speed heater problem. This is what has been done??? Anyone come across this problem? The interior fan only works on the slow speed! It does switch off when the 'OFF' button is pressed and comes back on when the fan speed knob is turned but only the slow speed (1st speed). We have fitted a NEW fan speed controller loacated near the fan motor just behind the lower glove box, passenger side footwell, no effect. We have exchanged the dash switch cluster/panel with a working one from my Supra, no effect. We have swapped the relay in the fuse box marked HTR, no effect. The air con works ok, all flaps seem to work ok when the AUTO climate control is engaged, the heated rear window works ok, the heater gets hot and warm/cold air comes out of the vents, all the switches and lights in the switch panel/cluster work ok. Car has not been messed about with the only thing fitted which is non-standard is an Alpine stereo CD unit.
Any pointers/help would be much appreciated.
