Default 1999 C5 Lumbar Pump

I removed and repaired my driver side lumbar air pump, but in the process accidentally broke the wire in the picture. Can anyone tell me what this is and does ? Where can I get another one ? And will the motor work without it or will it burn up the motor ? No luck at the auto parts stores.

that is a capacitor, you would need to take it to an electronics parts house to get a replacement.
The motor will run without it.

Thanks Gary. I'll try that. Wish Radio Shack was still around.

As stated it's a capacitor, looks like the size is written on it but cannot quite make it out, maybe 15 micro farad. You can run without it, it is there to reduce interference to close by RF devices like your radio.

Are you saying you can't solder on the capacitor?

Not sure where you got that idea, but no I am not saying that at all. I am saying, you can post a better closeup of the broken capacitor and maybe we can determine the size so you can order a replacement on Amazon OR you can cut the broken one off and use the pump without a capacitor.

I guess I just like to try and fix things, when possible. In this case, I don't know if it's possible, or not, hence my question whether you were saying it can, or can't, be done. You'd probably have to use a very small (measured in watts) soldering iron, or the excess heat could probably damage the capacitor. I guess if it's cheap and easily sourced, a new one would be best.......

I think I get what you where saying now, you are thinking of trying to resolder the broken lead to the capacitor. If there is a bit of lead left on the capacitor, yes you could do that. That is a tantalum cap, so if there is no lead left (usually they break right at the cap) then it is trash and requires replacement. Again, you can run the pump motor without the cap and it will be fine.

If you can do as you're saying, then running it without it is probably what I'd do. I wonder why there's a capacitor there in the first place, maybe to help start the little motor? I've never seen capacitor start systems on anything except larger motors, but I certainly don't proclaim I know everything, and I certainly dont. If it works OK without it, so be it....

Why the cap is there
it is there to reduce interference to close by RF devices like your radio.

OP, sorry for some reason I thought Grinder11 was the OP since he was asking all the questions.

So is 154 the only marking on the cap?

Actually, I checked that number, looks like a 150 nano farad ceramic capacitor, which can be looked up as a .15 micro farad as well. There are some assortments on Amazon that will contain that size or very close.
