Fan speed ,keeps gettting faster than normal


SC4HUNDO

Recommended Posts

ok, hope im following the rules for this forum.

I have a '95 SC400 and I have several minor problems, first ill ask about the climate control

The Climate Control will not run the fan speed properly, even when i choose to use manual control for the fan speed it will always blow out at full speed, sometimes the fan will slow down to the selected speed but then 20-30 seconds later it will go full blast again. The whole time the display shows the selected speed, but the fan spins at full speed. ANY ideas would be appreciated

thanks

I moved this from the other thread as that one is for just listing prices and other problems with the resolutions already done.

Your problem is eitehr in the wiring or the fan motors switch.

It is getting a variable power increase changing the speed. In order to trace this problem you will need a schematic guide.
