My 1993 SWB has a heated windscreen, which is apparent from the filaments visible in the glass and the presence of the heated front screen (HFS) switch on the dash. When I depress the switch it illuminates, I hear the relay click under the driver's kick panel, and after one second the switch goes dark and no power to the HFS.

I bought a replacement HFS timer. This thing:

Having removed the driver's side kick panel I cannot find this part. I found the black HFS relay as well as plenty of other relays and timers, but I can't locate this timer. I can't find any diagrams in my copy of RAVE that show where the timer should be. I would be grateful for a detailed description or - even better - a photo or treasure map that shows its position. It may be possible that I'm looking in the wrong area altogether.

Thank you for the diagrams. The part in question is labeled as #9 in the list and the image. When I compare the diagram to what is behind the kick panel on the driver's side in my vehicle, there is nothing in the position where #9 should be. No existing timer unit, not even a space in which to plug one in. It's just empty. It's not a small part that is hard to find, it should be in plain view, yet there is nothing in that space. Is it possible that the location was different for the 1993 model year?

Okay, here is a guess at a partial solution. Both photos of relay area next to steering column. First photo shows the bank of relays. I removed the front row from their tabs to show the back row (closest to the firewall). It's obvious where the heated front screen timer should go: right between the two yellow ones. But there is nothing there for it to plug into. Second photo shows wiring coming out of the harness and terminates in a 30A fuse. So perhaps a previous owner pulled out the timer (and the receiving end) and connected the wiring to the fuse as some halfass workaround to an issue with the screen. Any other theories given the evidence?

Does your oil pressure light work? I ask this because the front heated screen is linked to your oil pressure. I'm guessing they did this to make sure you couldn't drain the battery by running the heated front screen w/out the engine running. If the ecu doesn't see satisfactory oil pressure, your front screen will only power up for a moment, and then cycle off.

Thanks for the additional suggestions. I found the timer, replaced it, and no change. The oil pressure sensor is worth exploring as the previous owner installed an aftermarket oil pressure gauge, potentially disconnecting/bypassing the sensor. The longer I own this Rover the more negligence I find.
