Heater distribution flaps

How do you un stick a distribution flap that sticks every now and again?It is now stuck again but was alright last night.Heat is stuck going to windscreen.
Thanks in advance.

Try cycling the distribution switches see if that frees it. There is a bodge you can do with a screw in the middle to open the casing.

I have tried cycling the motors no luck yet, also sprayed silicone spray down trough pollen filters with heater motors running to try and un stick.If that does not work how do you do the trick with the screw?

You may as well spray it on the roof for all the good that will do. Tightness will be either in quadrant pivot or in bearing the rear flap shaft pivots in, notably the drive gear bearing itself. You would have to put a serious amount of silicone spray in the pollen filters to get near those. Do a search for screw trick it has been covered many times.

Very good lol. Seriously though it only sticks when we get a sudden temp change once it frees it self it is ok with no problems until it gets cold out then sticks for a couple of days.( will chuck tin away)
