Switch Pack Module Failure...

Well it finally happened... seems like my switch pack is on the fritz. The parking lights/tail lights/dash lights won't light up on my 2005 Elise. I haven't check the fuse (16) which I will - but I'm expecting the worst.

For the past couple of years I've had LED rings connected the parking lights. Does anyone think that the LED rings caused the switch pack to fail? I know the switch patch module is destined to fail... but if the LED rings contributed, I want to take them off before I get a new module. Does the current drawn by the LEDs go through the switch pack?

Any recommendations on where to order a new switch pack module?
Thx

I doubt the LED's had anything to do with the failure. Their drawn current is much less than that of the OE incandescent bulbs. Also the switch pack failure will effect your A/C. My guess is its either a fuse or connection issue to affect both exterior lights and the dash light.

Thanks surferpkt for the response. The AC blows strong - therefore the switch pack is OK? The fuse checked out ok. Next I'll test the parking switch itself - gotta swap the LED in the engine switch that's gone dark.

Not sure what to look for after that...

Mine went out on my 05 Elise last month. Any idea where to find one, stateside?

When my switch pack gave issues, it was only one relay in the pack (side markers and gauge cluster backlight). I simply swapped an unused relay from another location in the switch pack and it was fixed. I also think it would be possible to use FETs in case too many relays fail and the appropriate double throw relay is not easily found.

This sounds like my issue (partial failure)... last night I hooked up my Battery Tender and the battery was so dead that the Tender did not register a voltage (red flashing light). I hooked up jumper cables and once connected, the tail lights/parking lights/dash lit up and wouldn't go out... I even pulled the parking light switch and they remained lit.

Sounds like a relay failure...??? I think I'll try to repair myself. I haven't tried to find a new pack yet.

Thanks Obeisance

My switch pack module is out!!! Nothing broken.

I'm going to try to replace the relay on the board. I ordered replacement relays or I don't have to un-solder two relays - I only have to replace the bad one... also replaced my engine switch LED bulb with a blue one... easy.

BTW has anyone relocated their switch pack? Seems like these's enough slack in the wire to get it behind the engine switch - should I ever need to access the pack again.

I bought a lot of relays (25) if you wanna pitch in, I'll ship you one.
