Heater control bulbs, seat warmer switches & tidying the audio install
10 minutes to get to this stage. I love how easy the centre console is to strip down on the Z3
Head unit & cradle removed for maximum access. You can see the heater controls have already been unscrewed.
Seat Switches:
There was an issue with the heated seats in that the drivers seat overheated, almost to the point of burning. A suggestion we were given was to swap the switches and see if the fault followed the switch.
A recent thread had asked how to remove switches from the dashboard, and a reply was made that you can access them through the gear stick aperture. Perfect chance to try and bust that myth, only to find it worked perfectly. Removed the gaiter and the rubber sound proofing block, and you can get your hand on to the bottom clip on the switch. Apply some pressure to the bottom clip and the switch moves enough to grab hold of and wiggle out of the dash!
The switches were, err, switched and on a subsequent test didn't get a repeat of the overheating. Both seats when put on high, automatically switched down to the lower setting after a period of time. Need to monitor this when it's back on the road in normal usage.
Audio install tidy up:
The head unit looks to have been taken out and refitted several times, with the last attempt leaving the cage bent up and not clipped in securely. Spent some time straightening it out, and on refitting made sure it was secure and the head unit didn't move around! The unit also had a USB lead from the back of the head unit which was tucked in behind the console, so I dropped this out of the console paneling in to the foot well. Seemed a shame not to make use of it!
Heater Control Bulbs:
We already have an article on how to change the heater control bulbs, so I knew what I was doing in theory. In practice it's a bit more tricky that it looks, and I still have the scars on the back of my wrist to prove it!

The difficult bit is maneuvering the control block to an angle to work on through the head unit slot.
The location of one of the bulbs. Didn't get chance to take a picture of the other one, but its on the bottom left side of the panel! In the picture above the second bulb is located to the left of the "Made in USA" yellow sticker.
