The no click may indicate a bad TS/high-low-beam switch, or maybe the click/tab dealie is bent wanky & not making contact (check before you look for a new TS/H-L switch).
That said, the lower voltage with LED often makes the stock relays malfunction, so you usually have to put in a special LED specific TS/beam relay/set-of-relays on older cars. Check with your LED headlight supplier.
When I did the LED exterior light kit on my 88 Westy it included that special relay, so you may need something similar. The one GoWesty sells may work & IIRC it's for sale separately, but I don't know if it will fit the 914 relay board, since the Vanagon relay board is changed from the prior Bay Window Buses' board - which was similar to the 914s.
Another thing to check is for faulty LED bulbs & connectors/sockets, as they will make all sorts of malfunctions. My Westy had all of the exterior bulb sockets replaced with new during the resto, but the RF TS one had 2 wires crossed & gave me fits with the LED/H-L/TS not functioning right, until I went back & rechecked everything to find that error. So your situation could be as simple as that too.
Lastly, you may have a situation where you need to convert ALL exterior lights to LED in order to get it to all work properly (including the fog/driving lights if you have them & IIRC they make an LED H2 bulb for them) - if you haven't done so already.
PS - I have standard Halogen 80/100 headlights on the Westy, but all other TS, Side Marker & Tail Lights are from the GoWesty LED Exterior Light Kit, so mine is a mixed set & works okay once the crossed wires were fixed.
Also PS - I think GoWesty might sell a Bus LED light kit, which may be a better fit for a 914. Try calling them on Monday to see, if you think it might be the problem with the relay. Gowesty.com
Good Luck!
