W124 E320 1994 Electrical Problem

[grantmackay80]

Hi there,
I have a W124 E320 1994 Electrical Problem. It started this morning when the window wiper kept going after I turned it off, then after work the arial stopped working properly, the car at idol danced up and down but the car drove fine,but tonight it started to lose power when you put your foot down but went fine at half throttle for normal driving, the heater also stopped blowing out hot air.

Can anyone tell me what the problem is please.

Thanks Grant
