How To Use a Jumper Wire To Troubleshoot Porsche 928 Relays To Close Power Windows and Sunroof

[@bartlett1389]

The pins 87&30 are true for any relay I have one of these cars in the shop and someone put a wiper relay in but as for a good solution you can use a standard relay as I did and it works just fine

Did you try contact cleaner on the contacts in the relay and also the slots in the fuse panel

[@GuysWithRides1]

Yes, not shown is that I often use DeoxIT to clean the terminals in the box and the relay. I'm told on good authority that given the age of the relay (38 years old), the diode is likely bad.

Are you aware of 928srus. They have everything

Hi Joe, watch my videos, and you'll see that I send a lot of cash to Roger and his great team. Unfortunately, he does not everything for 928s. This relay was one of them.

Assuming you also checked 928 International. They list 928.615.126.00 @ $59. If that is correct one for yours.

Hi David, thanks for the tip. I currently have an order with ECS Tuning, claiming it will ship on October 5. 928 International will be my Plan B.
