306: problem solved, problem gained

I fixed my problem with the immobiliser/alarm (see "306 alarm/immobiliser
probs?")

I think I also know why the battery went flat in the first place, thus
causing the alarm and immobiliser to kick in once battery was charged/jump
started.

There is something dodgy with the electrics, and it is intermittent, but if
I have the car parked, and no key in the ignition at all, sometimes, I can
turn the car heating fans on, and the rear window screen heater, and these
usually only work when the key is in and turned round two clicks.

The problem of the rear heater being able to be turned on and off, even with
no keys in the ignition seems to have disappeared but the fan related
problem still remains, albeit intermittently.

I have made sure that when I lock my car at night that all the lights, and
there switches are off, inc reading light. the radio is off, as is the
heater fans and rear windscreen heater.

I also got the battery changed this morning as when the guy came to jump
start me I asked him to look at the battery and he said it looked like it
was running on only 2 cells, so after he had gone I went to an independent
motor place and got it changed.

Even with all the electrics off yesterday, the battery still lost enough
power somehow for it to need jump starting this morning. I am not sure if
this is down to leakage somewhere, or a bad battery.

I will see if the car is ok tomorrow morning.


Any ideas on why I can have the heater fans on even though the car is
"completely off"??
Sometimes I can hear a buzz/crackle sound coming from behind the dash when
the car is "completely off" too, but no relay clicking on/off. It is
strange, as all these problems developed overnight on Thursday just gone
(5th feb).

Sorry for the long post, any ideas?

Have a look at the boot light?

Common problem on Peugeot's

Scoob

 

thanks, should i just check for a good connection or something else?

 

known problem on the cooling fan circuit can cause this,the multi connector
to the ns of the radiator melts and shorts connectors together
i usually cut off this connector and solder the wires together

 

hi, my problem is not with the radiator fans, but the fans that drive the
heating to the car.

 

Scooby, I disconnected the boot light and just placed it back in its
housing.

I think it is a bit strange how the heater fans can be turned on and off,
I.e. through 1 to 4 even when the car is off though, but as said, this is
intermittent.

Car was ok this morning though after not using it for 21 hours, so maybe the
new battery solved things, and I will just have to make sure EVERYTHING
electrical that I can turn off, is turned off!!

 

feed back to aux ign circuit
i would still check it

 

ok will do, so i should check the connector for the radiator fan to see if
it has melted...?

 

no the inter connector harness lower down where it goes through the trim
next to the radiator
