Heater blower (puzzled)

[elchorro89]

My heater stopped working on 1,2 & 3 many years ago. Instead of sorting the issue I just used it on number 4 for a good 2 years until that decided to pack up as well.

before it all packed up its worth noting that the blower made s noise as if it just needed oiling s little however I now think it may be more.

yesterday I replaced the heater fan transistor expecting to regain use of 1, 2, 3 and 4 speeds.

However nothing at all, it doesn't work at all, does anyone have any ideas here. I've followed and inspected all the wires and they all look good.

im a total novice with cars so I'm just guessing here but does anyone thing the fan blower needs replacing or am I barking up the wrong tree here? I'd hate to buy that of its not needed as its £169 for a uni part.

 

thanks

The first thing you need to determine is if your still getting power and if your getting anything at the connector for the fan.

Basic things first such as fuse and visual inspection. If that's all ok, stick a multimeter on the plug for motor and operate the switch. If you get voltage there, you've probably got a faulty motor.
