Nissan/Datsun Versa: 2008 Nissan Versa SL. Blower fan will

Customer Question

2008 Nissan Versa SL. Blower fan will only work when switch is on level 1 and level 2. When on level 3 and level 4, the blower just stops. It's not a resistor or fuse problem and the motor sounds fine. Could it be related to the physical switch?

Hi there!
It sounds like the switch has stopped supplying ground on the higher settings. Normaly the blower will only work on the highest speed if the resistor is bad, because at high speed it bypasses the resistor all together. This does indicate an issue with the fan switch itself.
Hope this helps!

Thanks! How would I go about testing the switch on this model? I have basic practice in using a multimeter and I've built computer circuit boards, would it be possible to repair the switch? Here's a link to what my fan switch module looks like once it's taken out:

Ok, first, check continuity on the highlighted pins in the diagram.
There is no repair or replacement for the switch only on this so you would have to replace the unit you have removed. Here is a link to the part:

Here is the diagram for the switch.
