cold air/draught

[relias]

Hello all, mt t25 seems to be getting alot of cold air coming in from somewhere under the dash, when going along, any ideas where from and where to look

Check the corrugated hoses that feed the end vents on the dash. If your van/heater is an earlier one, they get fresh unheated air all the time, so closing them won't stop the air rushing in if there's a leak. They sometimes get disconnected at the heater unit end too; a bit of a pig to get pushed back on but worse on the later type where the driver's one is tucked up the side of the servo.
A torch will help you to see what's going on under there!

Take the front grill off and check all the rubber grommets are in place on the bulkhead and nobody has added any new (open) holes for anything.
