turn indicator.

[minesa240x3]

Hi folks not been a v70 owner long so please be gentle.
Very happy with the car thus far but last night it developed a fault!
The left hand indicator has stopped working? And so has the hazard lights,strangely the right hand one works just fine.
When the stalk is pushed down for left it clicks the relay just once but dims the dash lights and the front bulb and wing repeater light up briefly but the rear bulb doesn't?.
The rear bulb appears to be ok,if it was dead would this cause the fault or would the fronts flash faster?

I sat up late last night searching here for answers but all were the hazard relay/flasher unit fault.

Could it be a short to earth causing the dimming dash bulbs?

Any suggestions much appreciated,oh and how do you get the hazard switch out as it doesn't look as though it just pulls out?
Brian.
