D4 heating -Cold on left side

Hi

Noticed today that the side of the cab heating is deathly cold. Right side
Nice and warm. Wife getting stiff nips.

Have searched the forum - I believe the heater matrix may need a
Flush. But can’t find any advice on how to do this ?

Keep your fingers crossed that flushing fixes it. If not, it's a new matrix, which *may* mean dash out. I did work out a method of changing it without. Take a look at my posts here

So drivers side is warm and wife looking awesome. You sure there’s anything you need to spend time and effort fixing? Very Happy
