The carts have an installed relay all that has to be updated is the circuit. ---

Thanks for the comments. I did forget to mention my Gem is a 2004. Before I look at alternate wiring options I would like to check my stock wiring to make sure someone didn’t mess with it. ( I just bought this one last week). Anyone have a pic or diagram of the wiring connections at the switch on a 04? Thanks, Jeff ---

How many wires? Can you post a picture? ---

It’s been a long time but I remember 5 or 6 spade lugs and more than 1 jumper. ---

This might not be the correct switch that came stock. However it does operate the blower and heater but only if you hold the switch in that position. Thanks, Jeff ---

It doesn’t say the amps anywhere on the switch and obviouly doesn’t have the same rocker switch but does say carling 0331. ---

Can you verify wiring and colors. Looks like center off and two functions. Fan both ways, high low? Or fan both ways, heat fan the other? Or fan high/low-heat both ways. ---

Hmmm this one has 5 spade lugs and intended for automotive lighting service. ---

While waiting to verify operation and colors. Here are some good candidates. The carling # seems not valid. It’s printed on many types. Do you recall 2 speed blower or 2 heat levels? ---

Thanks Inwo. My switch actually has 8 spades connectors, 7 connected and one empty, wired very similar to mine but has an additional blue/purple wire and no black wire. I will try to find colored pens and draw it up. Thanks, Jeff ---

Couldn’t find any color pens but here’s how my switch is wired. I made a mistake in previous post there is a black wire, thought it was originally brown. The switch appears to just be a 3 way heater, off, defrost. Part number on the harness is 0106-00672 Thanks Jeff ---

Would you consider sending me the switch? As it still works, I could ring it out, post the results, and search for a replacement. Or Rodney might do it too. He has more direct knowledge of Gems. It’s starting to look like a specialty switch, requiring a rewire per Rodney. I’m up for the challenge!🙂 I’ll draw another and you can tell me the colors. ---

So is this a typical failure mode of a switch to change staying in position to momentary? Thanks, Jeff ---

I’ve seen it before. Not common. Is it center off? Or off-on-on? ---

Correct center off. Heat up. Fan down. Spring to the center when under power and when unplugged. Thanks, Jeff [Previous page](https://community.electricforum.com/t/heater-switch/5500.md?page=1) [Next page](https://community.electricforum.com/t/heater-switch/5500.md?page=3)
