CLIMATE ONTROLLS AND FAN DIED SUDDENLY. GOT WET SOME TIME AGO. DOES THE PANNEL HAVE A RESET IN BACK? DO YOU THINK THAT IS THE PROBLEM?

1993 Lexus ES 300 • 170 miles

No digital display, no air, no heat, no fan. Died suddenly. Any suggestions? Checked fuses, but not relays. Can't find them.

Does not have a reset. Most likey it is fried. Better find one from a salvage yard.

Relays will be in the main fuse panel and in the underhood relay box.

Power to unit is through ignition circuit via
Gauges and Cig/Radio fuses.
The connection to the ECM-B fuse is for back up power to remember trouble codes so probably not problem.
A/C power transistor is for controlling and monitoring blower motor, but has nothing to do with simple display.
Don't know if you could have melted/shorted it somewhere in the connector without blowing a fuse first.

Happy hunting, grab some extras of those pesky display light bulbs from any broken A/C control units you find(the ones that Lexus wanted $10 a piece for when I first bought the rig (and the yard let's me have em for free)
