Richardtr3a Posted January 28 Report Share Posted January 28 I was out in the TR this morning and stopped to look at the map. The ignition was off and the heater was still blowing air. It turned off on the rotating control and was working well. I am sure that the supply to the heater blower control should only be live when the ignition is on. Where should the supply start from so that is only live when necessary?? My wiring diagram is no help. Thanks Richard & B Quote Link to post Share on other sites
stuart Posted January 28 Report Share Posted January 28 As a heater on a 3a is technically an "Extra" its normally supplied from a green off the fuse box so its an ignition controlled circuit. That wire is often taken off the wiper green feed. Stuart. Quote Link to post Share on other sites
Richardtr3a Posted January 28 Author Report Share Posted January 28 Thanks for the fast reply on a Sunday. I have has a look at the fusebox and I can see the three green wires. I tested them and they were only live when the ignition was on. So tomorrow I will try and find where the existing cable is connected and may end up with a new short length. If I am successful I will move on to the next problem. There is always a list Richard & B Quote Link to post Share on other sites
