just bought a series 3 truck cab. Although the heater is working it is blowing much harder on the pasenger side front window than it is on the drivers side. How do you get to the air ducts to check if there is a simple blockage.

You are lucky, my heater has rusted right out and the waterbox is leaking. I will have to remove one from a donor. Here is a photo.

What he said. The replacement is a 2" (I think) diameter piece of flexible pipe (like that used for fish pond pumps). It's a bit of a bugger re-attaching it, as there isn't much space if you just pull the binnacle out to the extend of the wires and there is a fair bend that you need to put in to get between the 2 oulets.

but the blower is on the passenger side, isn't it? So that side gets first serving of the available heated air. All mine have had better heat on the left than the right. Of course, if there's no heat at all to the driver's side, forget what I just said...

I took out the lower dash and fitted a small metal 'bucket' from feed mill over the opening in the bulkhead.Then drill 2 decent sized holes in the bucket and screwed in some new tube to the heater vents.Its better than it was as the passenger side is completely clear and drivers side about 2/3 clear.

Definitely the pipe behind the dash has either come off or is missing.
