Question about power seats

[slim_john]

i recently purchased 99 trans am ws6.

i have question about the power seats. in the morning i adjust the lumbar support and the lateral (side) supports, the wierd thing is after the car has been sitting for a while the supports need to be re adjusted?

is this normal, if not what should i check to try and fix.

I get the same thing too, been that way since new. Not sure if its a defect, or if the bags inside naturally let air out over a short time.

Hopefully someone else can chime in on this.

Hmm I haven't checked but i'm pretty sure mine stay the way I set them on my 01...it still feels right...

yeah, mine "deflate" too-not a real biggie, makes you feel kinda warm in fuzzy when you readjust them though =)
