Hi , just bought a 306 estate auto (R Reg)

The previous ower has taken out the stereo , but thankfully the plugs are intact and not been vandalised

However whilst i was looking in the whole i noticed another plug with 5 small cables

Black , Blue, yellow, green and white

Can anyone tell me what it is for ?????????

Further information i have is that the heater blower does not wotk (however the aircon switch and recerculation switch do switch on ) so i therefore have assumed the fuses are all ok

And the cruise control does not work either

Any help would be appriciated

regards

Mark
