Hi all, I'm new here and trying to fix my daughter's first car. '09 500 with a blower motor not blowing, so have changed fuse and motor with not luck, so now I need to replace the resistor as my next option. I've searched everywhere on the internet, but only managed to find that you can get access to it (up behind pedals) with a piece of string and and a long socket. Does anyone have any advice or have successfully replaced it? Thank you for any help

Technical HELP! Blower motor resistor
Hi
Is the. Heater push button.. Or twisty knobs?
Worth checking the fan actually runs at this point
The fan should work on max just not the slower settings as the resistor is bypassed on full?
Just took out the blower motor and connect both terminals directly to the battery and it worked... so I know that's ok. Changed the fuse in engine bay marked 28 with a new 30amp fuse. On the 'twisty nobs' light works for air con so would like to think the unit works.... but no idea how to check thatHi

So I'm sure I read somewhere that the standard is it to be on full, but sometime cannot work at all if the resistor has gone
Grovelling under the dash drivers side it is then, whilst you're thre replace the cabin filter as it too is a PITA to replace and often just left, look for about 4 wires going into the ducting higher up that's the resistor bank

Use a multi meter on the wires to test for voltage, note it may be on the negative side not sure ?
Looks like a thermal fuse on the end if this has gone that would explain things

Just look for voltage at the fan
12v on #4
9v on #3
6v on #2
3v on #1
That's what the resistor does
if it was pushbutton ClimateControl
electronics control the speeds..
(No Resistor Pack)
Burnt terminals / crispy wiring is not unusual at , or near, the resistor pack
Only when under load, I suspect the thermal fuse on the resistor pack?Just look for voltage at the fan
12v on #4
9v on #3
6v on #2
3v on #1
This is the same company selling the same thing but cheaper?

No, just a struggle and small hands required a good torch will really help, at least you can identify the plug going to it now?
If your above small in size then though its extra work id recommend removing the drivers seat to give yourself some extra "wiggle" room!
That was a horrible job, seat out and about two hours fiddling behind pedals... resistor changed and still not working. I'm no electritian, so I guess I need to take it to someone else... unless there's something else I should try now. So fan and resistor are good/new.
Shame after all that work! let us know how you get on!
The control knob, does it feel right when you turn it?
If you're not good with car electrics get a auto electrician in.

Yep, control knob feels fine, turns freely. Pulled the relay and the pins looked a bit dirty so cleaned them up, but no luck there. Have borrowed a circuit tester and am going to run 12V through the relay and check that works. Otherwise yes, I think I'll have to admit defeat and take it to a real man.
Isn't there a Maxifuse in the fusebox near the battery?

Sure you didn't pull the engine cooling fan relay? Don't think, can't check at work, that the blower has a relay, but will have one to control the ac if fitted.
