Heater blower cuts out

Recommended Posts

Can I have some advice please...

Recently bought a VR6 Storm and the interior heater blower keeps cutting out very randomly.

It sometimes comes on fine when you first start the car up (all 4 speeds) then after you've been driving for about 3 minutes it just stops working.

I've replaced the thermo resistor, checked the copper plate behind the dial, and it still just randomly cuts out when it wants to.

Not sure what I should check next - It doesn't squeak or rattle, the 4 speeds work fine when it's on... I'm at a loss....

 

help!

I was going to suggest you check the pressure that the copper wiper has onto the copper strip, it gets very hot and this may make the wiper lift and break connection but work later when it cools?

Good idea... any ideas how I can bend/adjust the copper wiper? I know how to get the plastic cover plate off the dials but the wiper sits under the copper plate which means I can't immediately get to it. Can I take the plate off?

Do you lose any other electrical equipment when this happens, like wipers, indicators etc. If you do, the load reduction relay is playing silly-bu@@ers and needs to be changed. It sits on the fuse board - I can't remember which position off-hand, but if it is that, I can let you know later.

 

Best wishes

No, no other equipment is faulty.. I'm begining to think it's a switch problem so I might invest in some copper grease. Does anyone know how to get the copper plate off the dial so I can grease behind it?

Also, does anyone have the part number for the fan unit so I can order one from GSF, just incase the copper stuff doesn't work....

The fan unit is the same as mk2 Golf (unless you have A/C) but you need to swap the resistor packs over... They are about £50 from GSF so I'd try the switch first unless the fan whines anyways...
