Heater blower resistor fault

Post by rutter123 » Sun Apr 13, 2014 9:27 am

The heat sink type jobby that sits in the fan blower housing, mine has an intermittent fault somewhere inside its plastic housing, i guess a dry or corroded joint? it is not the plug as i am getting same voltage both sides of this but a break going to the heat sink, can the heat sink be removed from the plastic to aid repair? as it looks as tho its only clipped in has anyone got a remedy for repair or had any success or other suggestions, thought i had it sussed as it was all good on test outside the car but once refitted, no go.

Or failing that anyone got one for beer tokens?

I'm sure one of those includes a list of transistor types that can be used as replacements if needed - if not I have such a list somewhere - I'll look it out if you need.

The PCB board breaks rather easily, as I found out. You can take it apart though and other people have effected repairs. I was fortunate enough to have a replacement used item so my only input is to take care of the PCB board.

The problem seems to have fixed itself overnite, after re-assembling everything it refused to work on sat afternoon, sunday morning switched on blowing lovely all the way, left it running pulled/wiggled all the plugs, gave it a few knocks etc etc all seems well, so for now will leave as is.

thanx to electrokid for the link seems i may have binned a few pcb's over the years for no reason.

I know last year NEAT autos in west drayton had some NOS pcb's for £20 as fitted on my tzdt.
