Got myself 2011 Ford Transit T330, 2198CC (ex-AA) with 192,000 on the clock. When I picked it up heaters were working absolutely fine for a few days and then it only started blowing cold air. Took it to the Garage he said was probably the pipe, so he squeezed it and an hour later was working again- took it back anyway and got a new one fitted. Worked fine for about a month and a half and it's gone again... Cold air on any setting.
Anyone have any suggestions? It's driving me mad as I use it for work.
Cheers
