OK, removed the pump today and it seems fine.

Question:

Should the two switches ( door lock and open trunk) still flash when pressing even if the pump is bad?

I just have the feeling I don't get power to the pump.

There is a fuse up front (I beleive it's #6), mentioning door lock relay. Where is that relay and how would I test it.

God I wish I had a service manual. Can anyone send me some info on troubleshooting this darn pump system?

Thanks,
Sab.
