Thom4782 Thank you for another speedy reply! I'm inclined to go with the blocked air tube idea as being the cause of the lack of hot air coming out of the side air vent and will suggest this to the garage once I've had a look under the rear boot carpet for any leaks from the coolant tank in the morning as there may be more than one issue going on here. Will post results of my findings later tomorrow.

Have just noticed you're edited message, thom4782.....so will need to rethink this through again now if the left side air vent is an input vent! Once I've done my oil check in the morning I'll be in a better position to see what is going on and will get back to this forum with my findings. Fingers crossed on the cooling tank leak!! Don't want to think about a cracked block or cylinder head gasket right now as that could be a bit more complicated, but if that is what is wrong, then that is what is wrong. Thank you again.
