I am in the throes of rebuilding my HVAC unit ('87 S4) due to a failed relay. That was simple enough.

I have also received and installed the Jager LED light bulb replacement. With just a little trimming of the LED base to allow for better seaating in the socket, the resulting backlighting (red) is great.

I have also drilled out the sliders, expecting much improved lighting there, as well.

However, it seems that my fiber optic lines have died. I have no slider lighting, and no fan switch backlighting, as should be supplied by the fiber optic lines.

Is there replacement fiber optic cable available from any of the Rennlist providers or their contacts?

I have ordered some fiberoptic cable from this source, and will report back on their products. Order quantities are reasonable for our needs.

Nice find.
Might order some of those for other projects as well.

I used a 3mm LED in each of the sliders and wired them in. The result was far superior in my opinion to the old Fiber Optic.

How did you get a 3mm LED into the slider without ruining the retaining tail of the slider? The fiber is only 1.5mm dia.

I can see replacing the larger fan speed-dial bezzel lighting fiber with a LED as it is 2.5mm fiber

The fiber arrived today.

The 1mm single strand coated cable is slightly smaller dia. than the OEM fiber to the sliders. It can be secured in a similar fashion as the original or bonded in some other way.

The 3mm multi-fiber coated cable is slightly larger than the OEM cable to the fan speed bezzle. The hole for the fiber can be enlarged enough to accomodate the cable, or the cable can be stripped of the covering and then it fits.
