Heating Problems

[Rudderham]

On my frends is200 his heaters blow drivers side hot and the other side cold even in the centre 1 hot 1 cold has anybody had this before and know why

Most likely air in the system. Needs bleeding through.

If it has dual zone I would say one of the servomotor flaps has failed, there are quite a few of them which control the airflow direction like windscreen and footwell and others which control the mix of hot and cold air.

Mine did this yesterday. I had it set to windscreen and feet, but had all vents open. Driver side was hot, center and passenger side were cold. Feet and windscreen were fine.

Don't want to sound patronising, but before bleeding the system, have you checked that it's not something silly?

servo flaps check that and possibly one has not opened just stuck

I have all spares for the above if you need one.
