Ok anyone who has a series I knows how frustrating it can be that the heater vents are automatically controlled so you have no choice where the heat comes from.

 

Series II models have a different set up and have direction control on the vents, series I can be converted using the later parts (ecu and control switching) but can be hard to get hold of and costly.

 

So this in mind for a few ££s and an 30 mins work a little known work around and you now can have fuller surround heat in the Winter months with warm air option at the centre vents.

 

All you need is a small two pole swith and a couple meters of 0.75 mm cable and two connectors.

 

Fit the switch where ever you want, the heater pod side does make sense, route the cables down to behind the drivers knee pad, there are twe large heater ductings there, the upper larger one has a sensor located within it on the left hand side.

 

Snip either one of the cables to the sensor and connect your new switch cable in series with the two ends.

 

Now what you have is a Winter boost switch that will overide the auto feature and give you heat to the centre vents lower vents and side vents all at the same time, the only down side is the heat will be at full even, however using the switch as a control you can self regulate anyway.

 

The difference in cabin heat up time and comfort level is surprising and will keep your fingers and hands toasty when Winter comes.

 

I will add photo`s of the set up and wiring diagram if anyone interested, the switch type and part no. etc.
