How do I fix the heater switch on a rover 25 1.4i Y reg
** First check the Fuse 19, 20A, in passenger fuse box (see manual- under steering wheel). then earthing connection E5 (Front LH inner wing.
**electricat connections are most accessable at Motor resistor bank, behind glove box (released by 8mm 2 bolts underneath ) Resistor pack in front of blower motor, 2x 6mm bolts. flick or squeese electrical relaese tab**
** Check the state of the motor speed resistor pack/ prone to resistor/resistor wire failure , which is behind the glove box,
The motor circuit is Green, live feed , to motor, slate black to motor speed selector (resistor pack), Output (slate or Yellow or Green or pink And Black) then Heater selector switch to earth (black).
- The feed from the motor is Slate/ Black wire. It pass through (or bypasses) resistor bank which limits the current through) the motor thus controlling. the speed. This has 4 connection slate grey from motor.
**Check 12v feed on blower Motor connector Green +ve , Slate Black to Earth. if ok, short Slate/black(Sl/Blk) to earth motor should run.
-Slate/B black (S/B) via No restor to switch, pos 4,
-Yellow/ Black (Y/B) via High resistor to Switch Pos 3
--Green/ Black (G/B) via Medium resistor to Switch Pos 2.
--Pink/ Black (K/B) via Xresistor to Switch Pos x.
From heater selector all final connection to earth are via to Black wire to earth on ineer LH inner wing.
