Interior Fan System

[motleyc]

i have a citroen c5 hdi estate 04

i have owned it now for 3 years

i have had a few faults with the car

1 is that when it rains drivers footwell gets wet

2 fuel gauge sometimes reads nothing even though tank is full

3 the fan unit and ac fan works for about 30 seconds when i turn the car on then stops

i then have to turn off car and re start and it works again ???

it is booked in to citroen to be looked at but they now say it has no warranty left because i have done 74k miles

the first 2 problems i can live with

but the fan drives me mad as when it rains the windscreen mists up and i need it to demist

i am a taxi driver and need the fan to work all the time

anyone have a similar problem ???

also i have had the brakes binding on a few times

untill i cleaned all the calipers now they are fine

Welcome Motley

 

With regard to item 1, if you have a look through the previous topics, I think that a grommet requires replacing near the base of the windscreen wipers somewhere.

 

I'm sure someone will be along soon to correct me and help on the others.

if fan display goes off & none of controls work as mine did, replaced a regulator, elec thingy, conn block with aluminium fins, think its drivers side footwell high up with green connector block. off top of head £90 ?

The problem with the wet footwell is the cabin air intake is below the driver's wiper spindle grommet so any rain that gets through drops into the intake box underneath the scuttle and runs down into the cabin. Applies also if any gets under the plastic scuttle at the bottom of the windscreen. I sorted it by removing the intake box, putting a wall of sealant inside at the lower back edge, put a lot of drain holes in the bottom of the intake in front of the wall of sealant, put sealant on the foam in the bulkhead where the box attaches so the foam is not porous and sealed the box where it attaches to the bulkhead. Then I fastened a metal plate over the intake box front mesh fastened to the wiper left bolt so any rain that got passed the grommet or scuttle is deflected away. I also sealed the scuttle against the glass and sealed the grommet in its hole and packed it with grease against the spindle. This was at the end of last year and it has lasted, unlike just sealing the scuttle and grommet which was first tried.
