My windos in my 2007 tundra will not go down. I have checked the fuses and took it to the dealer and they tell me it is the Junction Block (main Body ECU) and want 1k for repairs. Ifeel they are trying to pull the wool over my eyes. Has anyone had the same issue

Not one fuse or relay shows it's for power windows. ? Probably controlled by a body computer - BCM. Would have main powers for the BCM. You could check these fuse for being blown, probably would be better to hook up a scan tool that can check for DTC'S diagnostic trouble codes in the body computer.

where can i locate FUSE BLOCK (J/B)?? ' B15 Sentra Forum

The body control module or body ecu is mounted on the back of the junction block at the left side of the dash where all the fuses are, in some case the entire junction block has to be replaced but not all, on some models the body ecu can be replaced by itself, contact the dealer for availability.

INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY (MULTIPLEX NETWORK BODY ECU) (POWER SOURCE)

The power window system uses 2 fuses, one main 30A "Power" fuse which is a large block type fuse found on the outer side of the steering column behind the dash in a large junction block, set on this block away from the main fuse group. The second one is a 10A "Guage" fuse which is a smaller blade type fuse found in the same location on the same junction block, but in the cluster of blade fuses on that block.

hello please help I got a tundra 2007 w/ no hazard turn signal & running lights (front yellow lights) HELP PLEASE all fuses check ok.

The "BCM" module on your van has become unreliable.
The BCM is the "Body Control Module" that all these systems go through. The issue is that these are cold soldered and after a time the solder joints break on the computer connection. It is located behind the fusebox underneath the steering wheel.
If you know someone who can solder. You can use an 8mm and a 10mm socket to remove the BCM. Open it up and resolder the joints with a soldering iron. After that everything should be fine.
It is easier than it sounds.

It is located on the back side of the underdash fuse box (junction block). You remove the lower steering column cover and knee blocker reinforcement. Then remove two plugs from the bottom of the BCM.
Remove the bolts holding the junction block to dash panel mounting bracket. Remove the junction block from the bracket. Remove screws holding the BCM to the junction block. Slide the BCM downward to disengage guide studs on jb from channels on BCM mounting bracket
