Thats a weird one.
1. Did they use to operate correctly before ?
2. Do you have a spare headlight switch you can try ?
85 86 87 and early 88 will work.
I wouldn't let the temp control backlighting eliminate anything.
If its not a problem with the headlight switch - then its probably a problem within the cluster. Which would mean you would need a replacement cluster.
You might can find someone on NCDubs website close to you that can loan you another headlight switch to try. Could also try taking your HLswitch out and spraying WD40 inside of it.
if you are very careful, you can separate the 2 halves of the switch (rocker side faced up, terminals faced down when you finally separate the halves, make sure to pay attention to the sliders orientation too) and clean/lubricate the switch contacts and slider..
i gotta tap on my headlight switch sometimes to get my headlights to come on.. had issues with the cluster lights also, replaced the bulbs and they have been fine since then..

Yeah, this switch was to blame for my tail light problem too.
I found a new one on the vortex for $12 shipped.

My headlight switch had problems until I pried it open and sprayed wd-40 in there.

got it figured out.
took like 4 hours for me to get to know how the wiring works in the car. bently was not useful. my cluster has different color wires.
used a lightbult pen thing. found the bad ground and re grounded it.

When you say " no hot air" you mean from the heater? Is the heater core bypassed?

it is not bypassed.
got the coolant lines hocked up and everything. maybe i have them on backwards?
i have theone to the right going to the cylinder head (top side of engine) the other down the metal pipe to the waterpump
prolly gotta re-foam the heater box..
oh doesnt that mean it doesnt work at all?

Congrats on fixing the dash lights.
Mk2 (especially diesels) are notorious for low heat output from HVAC.
Your Tstat and coolant are probably fine.
Most common problem is the blend door (flap) that diverts air to flow only over the heater core. It has foam to seal it to. Usually you have to take the whole HVAC box out and repair / re-foam the seals and stuff.
I've never done one yet.
But have one in need, and know of a few others that need it.
I've read of folks glueing or duct taping a cut-out section from an antifreeze jug over the door. Or just duct taping it entriely. Might be a walk through pictorial on Vortex.
There is a walk through DIY on odometer repair on Vortex too.
