I recently overhauled my cars motor (200is) and send it for a spray job, After reassembling the car there appears to be a overheating and electrical problem. all the electrical stuff are working except for the front and back wipers and the air-con and fan system (neither of them will go on and I do get voltage at the wiper motor) as for the overheating problem the fan does go on but the car overheats to just under max and then stays there.
