Car: BMW 735i - 1991 model.

Problem: Recently whats happened is that the heating system on the passenger side has stopped working. When I say stopped - all that comes out is cold air.

This car has two heating independant heating settings - one for the right hand (drivers) side, and one for the left hand (passenger) side. No matter how much I twiddle with the temperature knob - only cold air is blown out the passenger side. Can anyone help.

Regards

Khalid

Go to this site and click on "IHKA Components" for a description of the system plus there may be documented fixes as well (there's a lot of stuff). Anyway, go here: http://bmwe32.student.utwente.nl/

If that doesn't work, consider registering at roadfly.org and post your question there. Johan, from the above site, is perhaps the expert on the heating and A/C of a 7-series.
