Ho hum....summers nearly over so time to get an old heater problem sorted out. I've had an ongoing problem whereby I can only get airflow to the windscreen and rear passenger vents regardless of what position the airflow control knob is in. I did get my garage to look at it months ago and they seem to think there was a problem with the vacuum control on the heater control panel. They said a new one from VX would be pretty expensive and if I could get a replacement from a breaker or other source, they said they would fit it for me.
Having gone for this option, the first panel I ordered was completely wrong (full climate instead of standard a/c). The second and third were both wrong as they only had 5 vacuum connectors and apparently I need one with 7. I was unable to locate a panel that had 7 connectors and sorta gave up for a while as I was still able to get hot and cold air in the car (just not where I wanted it).
So, here are a few questions.
1) Would this problem definitely be caused by a defective heater control panel or are there likely to be other causes?
2) If there are other causes, what could they be?
3) Why do some Omega's have 5 vacuum connectors and others (like mine) have 7?
4) If it is the control panel, anyone know where I can get one with 7 connectors (my control panel has the 4 rotary controls) at areasonable price or do I need to go to VX?
I'm very reluctant to get this sorted out by VX as it's likely to cost me an arm and leg
Any good advice would be much appreciated.
