Default Lumbar bladder Fix?

Anyone have a write-up of how to fix the lumbar bladders in my 87 coupe with the sport seats option?
TIA! :cheers:

Are bladders leaking, or is the pump faulty? If you have a faulty pump, there are two TECH TIPS in the C4 section.

I fixed the pump gasket using the tech tip by replacing with a piece of rubberglove and it works fine now.

I did the rubber glove fix - it only held up for a few months and failed again. :( Maybe the rubber gloves weren't high enough quality? :confused: There was a website a long time ago which had the source for the replacement rubber piece. I can't seem to find it anymore. Does anyone know? Next time I take the seat bottom out I'm going to try the fix with the real part and see if that holds up better - if I can figure out who I need to order the part from that is. :lol:

Juliet, here is a TECH TIP that uses an old inner tube instead of a rubber glove. The inner tube is much thicker and is much more efficient than the original diaphragm. If you are not interested, I can do a little research and provide a source for a replacement kit (about $35).
