Got a leccy problem with me van Im sure its s simple soloution . The problem Ive got is if I have the wipers and the heater blower om full at the same time it melts the fuse (number 11 in my van) as I have the older style fuse box it tends to make a bit of a mess. Last time it done it I caught it just in time as it was burning through the plastic cover.
Now the offending fuse is joined to relay 24 with a thick black/yellow stripe. Then has 3 wires coming off the other end. Theres a thick red wire feeding in to the relay which I guess is the live feed. Now I performed a controlled experiment earlier and with the wipers and blower running together the black wire form the relay is getting warm and the fuse is getting hot .
Number 24 is a voltage reduction relay, now the fact the wire is getting warm and the fuse hot mean that theres not a lot of voltage reduction going on .
The relay has 11-82 printed on it if thats its made date maybe its time to get a new one?
thanks in advance

Simple answer = it is almost certain that your heater blower motor is on the way out = common problem.
The bad news is that it is a pain to get to, requiring the entire dash to be removed.
Details on "how to do it" are in the wiki

Agreed ^^^^^ but old style ceramic bullit fuses are troublesome anyway, as they rely on the sprung contact pressure of the holding terminals to give a good enough contact to the tappered fuse ends. Any tarnishing or diminished tension, results in resistance. Resistance causes heat and there you have it.
As a side note* make sure you have good quality ceramic fuses and not the cheap plastic ones that melt.
Yep, you need to replace blower motor. No doubt about it. Its drawing too many amps (because its past retirement age) and made wose by wipers on same fuse. However, you can at least avoid the horror of losing your wipers in heavy rain when the blower takes out the fuse by following my fuse mod:
Now I know the problems there I avoid using the heating and the wipers at the same time, the dash has got to come out when I repair my windscreen holes so its no big problem to do the job then.
Ill have to hunt for these ceramic fuses as the ones in the box are all the cheapo plastic ones

This was alleggedly said by the head of Namco in response to being questioned if computor games influenced kids. As a teenager of the 90's I find it quite apt, its my favourate quote ever

On the fuse front, try and get some ceramic fuses that have copper contacts as the standard aluminum ones tend to oxodise. I bought some on Amazon. Much better and cured an overheating problem. Good luck.

Once the heater blower has become a heater in its own right through age, its all too easy to flick both motors on and lose both in my experience. Either split the two as outlined or remove spade terminal for blower motor at fusebox until you get around to removing the dash - or remove blower switch as a reminder not to use it. Of the two, the wipers have to be the most important and must function for the vehicle to be legal. Putting the two on one fuse was a quirk of the early fusebox (mine was the same) but its fairly easy to put right. Good thing to have each on their own fuse as there is nothing worse that the wipers dropping out in heavy rain on a motorway because you inadvertently started the blower. Been there - have the T-shirt.

totaly agree with you re splitting them, Ive been out having a play and fortunatly someone fitted a little fuse box on the side of the origional which has a spare terminal with a live feed to it , so the wipers can go there. My first of two questions is does the wipers feed need to come through the relay 24 to reduce it as per the origional ?.
Second question Ive had a go at refitting me headunit tonight and its works fine on the first turn of the key, turn to start the engine and stereo goes off and van turns over but wont start, disconenect stereo and van starts . I take it the stereos drawing to much power stopping the van from starting , If so am i better of running a seperate power wire from the battery with a inline fuse and cut of switch (to prevent stereo beeing left on ) Or will I still have the same trouble?

On the fuse front the ceramic fuses I got were made by 'Consuma bulbs'. I bought a mixed pack. Not all had copper connectors. However, if you cannot get copper ended ones use a smidgin of wd40 to clean all connectors and put new aluminium ones in. That will remove the corrosion that causes the resistance and the new ceramic ones will not soften or melt. Good luck with your other problem.
