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

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.

Peugot 407 heater not working

You more than likely have a problem with the temperature control blend door inside the air ducting, this door sits between the heater core and the AC evaporator core and mixes the air for the desired temp at the registers/vents. More than likely it is sticking due to being warped from heat. To replace this door and its actuator requires the dash be removed from the car.

Heat blows cool air

Could be the thermostat is stuck open. If you have a gauge does it warm up to the normal range? If it does warm up to normal operating temperature check the heater hoses near the firewall to see if they are getting hot. If they are getting hot then most likely you have a baffle issue in the heater box.

Well i have a 2001 S80 my AC is blowing cool on the passager side and hot on the driver side what can i do to fix it.

You will need to replace the Acuator for the Internal Baffle inside your dash for the Driver's side A/C vent. The Actuator is not opening or closing the baffle to give you hot or cold air.

A/c and heater

Is it leaking antefreeze?
The thermostat might be gone or needs a bigger thermostat
It could be a vaccum leak for the drivers side blowing cool air and the passenger side blowing warm air
Does it have dual air control switches one for drivers side and one for passengers side?

Jeep Blowing Cold Air

This has happened to me on my 1998 Grand Cherokee for the past couple of years. It is intermittent, same problem with the a/c blowing only hot air. My mechanic said it would require taking the whole dash apart which would cost a couple hundred bucks. He said it was a baffle that was getting stuck. So now, when it happens I hit under the dash to the right of the console with the palm of my hand. It will loosen the baffle into place and then it works fine. Not only that, getting out my frustration gives me some satisfaction. :-)
