Strange Behaviour Of Washers

[sifaan]

Hi!

 

I had the following issues and got the Com2000 replaced

 

1. Airbag fault message (can clear, but usually reappears on steering wheel rotation)

2. Horn stopped working

3. Rear wiper doesn't rotate when set to wipe (apparently it didn't generate any signal from the switch)

4. Rear wiper does rotate when set to wash, but water appears only from front (even with a new washer pump)

5. Front washer mode rotates the wipers, but no water

6. Front fogs do not light (bulbs are physically OK, front fog indicator on dash comes on though; also rear fogs work as expected)

 

After replacing the Com2000,

1. airbag fault is gone :)

2. horn is working :)

3. rear wiper rotates when set to wipe :)

4/5. rear washer drives water, front washer doesn't. not sure which side gets supplied but presume its the front, like before. garage has currently hooked up a t-joint in the plumbing so I get water from front and back.

6. front fogs work, but also activate the washer pump :)

 

I think there is possibly some wiring issue (the fuse box had been replaced after it burnt out, and some wiring parts had been repaired) - perhaps the wiring to the washer is reversed (that's maye why the rear washer swtich supplied water to the front); but I suspect there's more to it:

1. why doesn't the front washer switch drive the washer pump (it does drive the blades though)

2. what's the connection between the fog and the washer pump (if there was a short, then the washer should activate the fog lights?)

 

a local peugeot enthusiast suggest downloading firmware to the BSI... would this help? any suggestions how to go about this (the garage/agents were not aware of this option)

My horn is lazy i have to press it 2 times before it goes bib bib by this time i am half way down the road in fact i think my car goes to sleep because i hit the lock button on the key thing ma jig and it locks i then come back 2 minutes later and it opens when i hit the unlock button now if i come back say 15 minutes later i am just standing there pushing a button like a prat. Also has a new key battery and did what Haynes says to jokey it back up to the car. But i don't care because well its just a glitch. Love to no why they do it tho
