Hi

My blower haven't worked for a long time on my 1984 Euro 928S. Only on defrost (slider to the far right). However the temp settings works - but only with the air that naturally flows trough the system at high speeds.

So I finally got around to changing the resistor pack - the old one was shot (se picture).

However the system still wouldn't work. Caused by a bad relay. I loaned a similar one from the fog lights (marked with "24" on top) so now the blower works and I can control temp and direction of flow.

However the blower works at max speed even if the dial is set to 1, 2, 3 or 4...it only shuts down when direction is set to the far left ("0").

So...where is the fault? The resistor pack is brand new from 928intl and I also tried with the old one just to check - but its still running at full tilt.

I have A/C delete of the affects anyting (or rather: the PO just pulled it out).

Suggestions are very welcome. And a part no for the relay would be great - just to double check that I have the correct one.



old and new resistor pack

Thanks

Lars, when installing the new blower resistor pack in both my '86.5 and '87 I had to reroute the pins, otherwise the fan would be blowing all the time.

This is an excerpt from Alan Moore (the resident 928 Electrics expert)'s post exactly seven years ago:

If you switch pin 6 with pin 8, it will work.

I hope this helps.

Scott,

Thank you for your suggestion.

My resistor pack is 928.616.101.00 which I guess is for the wrong year then :-(

I just tried a quick switch of 6 and 8 before a rain storm drove me inside. But its still running at full tilt.

However I just found another Rennlist guide that suggest that 8 should insulated and 6 moved to 8 (enclosed). I'll give that a try tomorrow.

Thank you for your help so far

Lars - you have the correct resistor pack - just move 6 to 8 as you have noted.

Thanks Roger, I will give it a try tomorrow. Its a start that the blower runs, but going at it at max speed quickly gets old :-)

On another note: I just sent you an email (sales@...) concerning the aftermarket GTS windshield noise killer silicone-thingie. After I changed all the old insulation the wind noise is suddenly much louder

Thanks guys! I insulated 8 outside the connector and switched 6 to 8´s place....it works!

(should have done this a year ago, but its nice to have projects)
