Nu Relic power window issue - Lateral-g Forums

Blitzer is the expert but I would shoot for minimum 30 reverse volts and minimum 30 forward amps. Forward voltage should be as low as you can find. The rest of the specs won’t make any difference imho.

Don's specs are good, I would only add that I would find one that is physically big enough to work with and high surge current rating. I would go with the SBX3040-3G as it meets all the requirements and is also cheap.

For the resistor the FVE030020E1R20KE would get the job done for less money.

Awesome! It's so cool and fortunate to get this kind of assistance, I will follow up with my findings
Thanks again

Fascinating thread...I dont understand a single word of it...but am amazed by what you guys are talking about and the fact that you found a solution!

I ended up using this resistor
https://www.mouser.com/ProductDetail/284-HS3001RJ
And this diode
https://www.digikey.com/en/products/...4S1-D3/5068422

They both qualified for the parameters we were looking for and the packaging was convenient for mounting.

The front windows now work at the same speed up and down.

Thanks again for all the awesome assistance

Those are some serious parts. You know what they say. Go big or go home….

Nice. any chance you can put up a quick draw of how its wired? Which feed which side of switch ect..

Sure I can verbalize it easier than a drawing, but the switch has 2 wires to the window regulator motor. One up and one down, the resistor is put in series with the power down wire and the diode is in parallel with the resistor. I had to play with the diode direction to get it correct.
Thanks
