Title: Heater Blower
Post by PJDavis on Aug 30th, 2014, 3:10pm
The air blown out of the heater has become intermittent.   I have tried a reset, and tried a different panel, still the same.   If I turn the left blower switch to full-blast it seems to work better, but anything below that and the blower cuts in and out at random.   It's driving me nuts!   No-matter where on the scale the switch is turned to it cuts in and out, temperatures are good.   At one very brief point, the 00 scale read 07 just for a split second, so is it the blower-motor switch bits under the bonnet?   If so, anyone got a good-un?   I also have a spare inside the dash bit with the ribbon cable coming off it, but would prefer not to b****r-about removing that part of the dash unless definitely necessary!

Any pointers valued

Peter

Hi Peter
I have had 2 similar episodes in the past
1 was due to worn /dirty potentiometer behind the climate control panel-improved by electrical contact spray, the other, which was more like yours
2 was due to a failed heater blower controller (the HBC)  and was cured by a replacement
Regards

Hey Glynn
I'm thinking it's probably the HBC.   I'll need to get one before winter really gets a grip up here.

Peter,
I thought you would be a foot deep in snow by now.! Soon that HBC will become urgent !

While we're on the heater blower - mine has the occasional small squeak or whistle at certain rpms - anyone have a solution or temporary fix that doesn't involved removing the blower?

Have a read of This page (http://www.fordscorpio.co.uk/cgi-bin/yabb/YaBB.pl?board=admin;action=display;num=1278660411). Read down and you'll see that Gozz has an idea for solving this by drilling into the cover. We did sort a similar issue on Gost's car at a meet once by simply removing the HBC and spraying WD 40 inside. Did the trick. Worth a try.  ;)
