Fan/blower motor voltages and help!

[Tom]

Basically i changed my heater matrix over the last few days but i dont even know if its working because i put the car back together now the fan wont work. Im going to rattle off what i know, then hopefully someone with electrical knowledge can help me out a bit, Just in that mood where i finally got the dash back on, home straight, havent drove it for 3 days and this happens so apologys for being grumpy
The day the heater matrix shit itself the fan stopped working on settings 3 and 4.
It did work on 1 and 2.
When i put the dash back on yesturday the fan didnt work atall, it was soaking, brought fan indoors wd40 and a radiator and it worked on 1 and 2 for a few minutes this morning then died.
With the fan plugged in i tested the voltage, black on a suitable earth and red on the red/wire/terminal of the fan motor. This read 6volts regardless of fan speed setting.
So i lost my rag called it a lady garden and came inside for cooked breakfast.

Its odd to stop working on 4, that kinda rules out the resistor pack as I believe 4 is a direct feed.

Are you sure the heater panel cable hasn't fallen out?

[Tom]

Definately plugged in :/

[Toms306]

Hmm, well in that case, I guess it's f*cked.

[Tom]

Thats the thing, not sure if the switches are f*cked or if the motors f*cked. The conections are that f*cking difficult to get at on the motor i cant bench test it. Thankfully this new fangled heat i have is keeping the windscreen demisted without the need for fans. But i need my f*cking fans back!

Meh, I still haven't fixed my blower, probably won'tget round to it either, just drive faster to get the air to flow through!

I reckon you've pulled/trapped/shorted a wire somewhere though tbh, thats what happened with mine, the wires in the plug won't stay in.

[Tom]

Really i need another one to test it all out on :/

[Toms306]

Hmm, if you have any local scrappys just see how cheap a motor/heater panel would be to swap in, if its not much might as well give it a go. Well thats what I'd do anyway as I'm crap with a multimeter lol.

[Tom]

Im fine with a meter its just i dont know what voltages are ment to be where haha... I may have to swap bits with others til it works
