Always check the simple things first...

[Vulpinity]

A little lesson for us all (or at least me!) in checking the simple things first...

Had no heater blower in my C5 for the last couple of weeks, so finally decided to do something about it a couple of days ago! Had a quick look at the appropriate fuse, nice and easy to view without even removing it fully, looked perfectly fine.

After much perusing of various forums, a new climate control resistor pack thingy was purchased, fitted, engine on, fans to full, and.... Nothing.

So. Dead blower motor it is then! Wandered down the local scrappy, clambered across various dead hulks of Citroens past and plucked out the fan-shaped heart of a rather squished looking C5. A few minutes rummaging behind the dash of mine, engine on, preparing to bask in the wonderful heatwave and... Nothing.

Randomly thought I would double check the fuse just in case I had popped it while poking around with wires behind the dash, so I pulled it fully out this time, and noticed some muck on the surface of one of the legs. Cleaned it off, refitted, and voila - perfectly working heater fan.

Doh!

Oh the pain....... We have all done it.
Hands up all those who have never overlooked the bleedin' obvious. Ah, nobody just as I thought

One of my best was an old opel automatic I had, puffing white smoke out of the exhaust. So I removed the box (a real pain as usual) and took it to a local auto repair place I had used before to have it rebuilt, I assumed.
They asked the problem and just changed the small vacuum chamber on the rear of the box, took 2 mins and could have been done on the car in the same amount of time. Do went home, got out the spanners and put it back

i would check/tighten up the terminals the fuse pluge into as well, as it sounds like they have overheated which will be caused by a bad conection/contact,

Its always nice to find a simple fix

As Malcolm says you will probably find the the 'muck' that you say on the fuse was actually oxidised metal due to the fuse overheating - very common problem on XMs.
