3 things to try
1. in the left hand side foot well, remove the trim at the front of the center console and make sure all the heater control cables and valves move as you operate the controls
2. small cabin temperature sensor - , passenger side, above and to the right of the glove box - grille about 20mm in dia. There is a small fan in the sensor to **** the air in over the temp sensor, but it can in rare cases gives up, and leaves the controller lost and it reverts to full heat or full cold. The fan is little brushless DC job, so you can't do anything with it - got to buy a replacement - which isn't cheap. As a short term, you can hang the sensor out of hiding place which allows it to work sort of. - if you can find a way to get it out
3. the heater matrix is lower than the feed and return pipes - mine was full of radiator sealent (radweld)
drain the coolent water and disconnect the two hose inside the engine bay that feed the heater matrix (they are on the passeger side if your car is right hand drive)
now give the matrix a good flush by sticking a hose pipe into the metal pipes that go inside the car - do this in both directions until clear ------ i had to use kettle descaler and radiator flush left over night in mine.
when you refill make a header tank by cutting off the bottom of a 2 ltr soft drinks bottle, remove the scew cap and wrap some tape around the top of the bottle, and stick it in the top of the radiator
fill the sytem and use the bottle to create a good head of water
make sure the heater controls are on HOT and bleed using all the bleed points
mae sure you bleed it all properly

renew the flexible hose connections at the tank end if fitted and not a plastic pipe going straight to sender unit .Sucking in air problem is one of THEM jobs .a right pain to find 99%of the time .but any flexible rubber pipes can and do go porous with age

Some garages are offering free diagnostics on AC systems. I'd try one if it's free.
They will then try and sell you a "service" - which is just refilling your system with a can of refrigerant.
Don't let them do this - It'a DIY job - cans available at most car factors.
