Argh.... the fan which I just DIY is not working le... last night smelled a burnt smell... so was from the fan.... just took out the fuse to check and it is working.... so left the relay ($7) or the fan ($25) which is spoil le... hopefully it is not the fan....

I realised that windscreen wiper cannot be used at speed of 140km/h... They will just plain vibrate and cannot wipe dry the window at all.....
