Vito W447 Issues

[Aaronn]

So over the last 2 weeks I've had 3 different issues arise with my w447 111cdi.

Firstly the blowers stopped working inside and the radiator fan is blowing full speed. The 10A fuse is fine and the only way I can rectify it is by removing the fuse for a minute then putting it back in and this resets the issue and it works for a couple of days then happens again.

Second issue is I'm getting a ESP & ABS fault which randomly comes on and goes away.

Now the final issue is the keys aren't registering to start the van, literally takes about 5 minutes of trying them before they register and the ignition turns on, sometimes I can take the key out and the engine stays running.

All happened in the last 2 weeks, do you think these are linked or separate issues? And any advice?

Thanks

The blowers stopping working could be the resistor pack
The ABS & ESP fault light could well be a low battery voltage
And the key issue, if it was me I'd contact these guys

It does sound like they could all be related, have you access to a code reader?

Thanks for the replies. I'm going to plug it in to a code reader tomorrow although it's just a cheap one so not sure if it will throw anything up. Yeah I think firstly I'll book it in to an auto electrician and see what he can diagnose. The keys have been fine the last 2 days, after disconnecting the battery, although I did get stuck for 3 hours and had to get the RAC out as the barrel just wasn't registering them. It was definitely the ignition switch playing up, just strange how it's absolutely fine again.
Where is the resistor pack located and is there a way to test it or would that show up on a code reader?

Not sure on a Vito, it's usually around the heater/blower area.

You might need a 'good' Mercedes reader to get a more detailed view of what's going on but it's worth a go.
