Hello,

I need some advice.... I replaced my dash board, all reassembled, had a fight with the steering wheel (4 attempts to get it straight) now naughty me did not disconnect the battery when fiddling with the steering wheel - also my battery went flat so i jumped it but put the negative leads on before the positive leads.

So, i guess that probably did it because i tested everything after the dash installation and it worked. I checked the fuses and they are ok, could it be the relays? anyway of testing them?

Thanks

Graham
 
Putting -ve on before +ve when jumping shouldn't make any difference.

Two options.

1. Look at a wiring diagram and see what would need to fail to cause both of those to stop working, but everything else to be fine (is everything else fine? Does the car start and run?)
2. Trace the faults with an AVO meter and a spare afternoon. You'll find the fault somewhere.

try a search on the 944 forum. I recently answered a similar problem and posted the electrical schematic .

 
heres a schematic

this might help with tracing the horn circuit

Power is fed through the relay to the horns and then to earth . That supply is constant and broken only by the switch in the relay.

When you press your horn button another live feed is taken through the relay coil through the horn button to earth. Whilst the second supply through the relay coil is earthed the switch in the other half of the relay is switched closed passing the supply to the horns.

In other words the horn push only operates your horn relay not the horns directly.
Simples
So you need to check the 12v+ power supply to the switch and the coil on the relay, check the fuse and check continuity of the wiring of the whole system and obviously the earthing to both the relay coil and the horns
 
having just chaned the indicator / wiper switck on my S2 I would guess you have moved the conector on the back of the switch. Check they are pushed on fully.
