I have a 2008 Sienna. Parasitic draw of 300 mA. The problem is in the engine compartment fuse box. The problem has now temporarily gone away but i think it will be back. I pulled relays and fuses, nothing. When I wiggled the fuse box it went away. Are there problems with the fuse boxes themselves or did the faulty relay happen to unstick for awhile? Thanks in advance for any suggestions

See post #3 as possible answer.

Engine fuse box and parasitic draw

2008 Sienna with 300 mA draw that has now disappeared. The culprit is in the engine fuse box or relays. Are the engine fuse boxes known to be bad in the Gen 2? At this moment the problem is gone after removing relays and fuses and wiggling the box. Thanks for all the advice in advance
