Blend Motors Problem P38 4.0

madbrit · May 4, 2021

I have a problem with my blend motors, they don't work, So I have taken my blend motors and distribution motor off the vehicle and connected a 9v battery to them and all 3 work fine in both directions.

BUT they wont work via the control panel, I have tried 3 different control panels and I cant get them to work with any of them.

I have again tested all 3 and they work fine

Any ideas anyone getting to the point of just wiring a switch to each

Thanks

do you have the book symbol? probably the potentiometer in the blend motor is dead and needs replacing, common issue

Easy to test I've just had the pot problem on my passenger side. Brown and black wires are for the power the other three go to the pot. use multi meter to see if you get any readings across them

I have 2 of these p38’s. And thenother one works fine with the book symbol. But the pots do show an erratic movement. So I have a load of these pots. So will change them all. Thanks. Will
Post the outcome

thanks
