wipers/washer pump/heater issue

Hi everyone,

over the last year I have been experiencing intermittent failures of several 12v windscreen washer pumps. Ive now started to get failures of both the wipers themselves and the heater/blower. This is making me think there has been a deeper electrical fault at play the whole time and not an isolated issue with the washer motor.

Has anyone else experienced this? Is it common? Any suggestions on where to look to source the root of the problem?

Cheers in advance,

Craig.
 
You know this ? Series 2 Fusebox
And, for sure, check the terminal connections at the wiper motor, next to it are the wire connections for the blower motor. Use special spray lube for electric connections, which cleans and protects. Check earth terminal under your front carpet (mine is RHS for a LHD drive car....).
 
Cheers guys.
No sign (or smell) of any melting but I'll take a proper look as Im nervous about this now. Might just book it into the workshop and get the fusebox replaced.
 
So, there doesnt seem to be any sign of overheating/melting. Strangely though the other day I had the car out and both wipers and blower were still not working, I touched both fuses and even turned them a little and both things fired into life. A short time later they packed in again and this time I merely opened the glove box and bam, on they came again. Does this suggest its just a loose connection somewhere?
 
Hi Craig,

Clean the contacts that retain the fuses along with making sure that the fuses are tightly retained.

If the problem continues, then you'll need to investigate further, but hopefully that will correct the issue.

quite common on the series 2 fuse box.

Often if the headlamps stop working you can roll your thumb over the fuse to rotate it and bingo lights start working.

There was an article where someone had made a clip that held the two parts tight against the fuse.

I have also though that a fixed connection between the tags at the back would help. Also if the terminals were tinned they would probably be less prone to oxidising.

You can buy aftermarket fuse boxes which is worth considering.
 
I never had any problems with my fuse box on my daily driver, it was still running the proper lucas fuses.
Its when the fuses have been replaced with smaller non gen type,or owners adding high power accessories to wiring on fuse box
without relays causes the problems.
The fuse box on my breaker car is still as good as new.

If my memory is correct, the problem with the fusebox is that the two sides of the clip are seperate, joined by the plastic box. When you start changing fuses they work loose then the heat of the bad contact melts the plastic and the fuse becomes even more loose. The clips I have seen go around the end to provide some clamping force after the plastic has melted.
