Hi, i have an ls430 2001 model 2nd option. Im having similar problems i could really use some help guys.
In my case i cant unlock my car using the remote, my fuel cap and trunk also wont open from either the switch inside the car nor the remote also my mirrors wont fold. I had both my driver side n passenger side fuse boxes replaced and also the fuse box in the trunk. All three were affected due to water logging caused by the rains.
I have checked the fuses now all are having current but i cant figure out why my electric function aren't working. Pls help me
