We left Monday for vacation and came home Friday night. While we were gone we got a couple good rains with wind. When i got back my 06 LX470 has no electricity. I thought i may have left something on and ran the battery but it is at full charge and 3 months old. I did go into a quick horn honk when i put the charger on. I diconected the battery cables from the battery and turn the ignition to on a couple times. Hooked back up the cables and nothing. Internet search says is may be a integration relay that is behind the fuse box. Last year after a rain i had electrical gremlins. My sunroof vent was clear last summer. I haven't checked that yet. I have an aftermarket roof rack and perhaps water is getting in there. What are my next steps? Put a dehumidifier in the cab? Or order a inergration relay? How hard are those to change? Lots of questions. Please help me.
