Wipers Won't Operate While Engine Running
 

Hi Team
New owner here of a 2003 986 and weird problem out of the gate. The battery has been replaced with a fresh unit and weird problem now......with the electrics switched on (engine not started), wipers work just fine, no problem. If you start the engine, wipers cease to operate.

I'm assuming it's something to do with the battery swap and just wondered if there's a procedure to go through or similar.

Take care,
Steve

Well - I answered my own question (doh !). Problem was a sticky ignition barrel whereby if the switch was in the electrical position all the electrics would work fine, then you turn the key further to start the engine (which it would - all good) but then electrical functions like the wipers wouldn't work, turns out that they key wasn't returning back to a 'normal' position......kind of makes sense now as I assume things like wipers would be interrupted to give max power to the starter motor, etc.

Maybe a symptom of the ignition barrel being on its way out ?.

Cheers,
Steve

Ignition switch is a know problem on theses cars.
Ignition barrel is most likely fine.
