RX300 CLIMATE CONTROL NOT RESPONDING


Recommended Posts

2002 Lexus RX300

But oh there's SO much more that isn't working...

 

What it's lost:

 

Door chime (doesn't recognize the key is inserted and door is open)

 

Dome light (doesn't work with door opening, however the individual little lights on the bottoms of the doors still work when opened)

 

Door locks (Neither the key fob or the switches work inside)

 

Door windows (They all work individually, drivers controls drivers, passengers controls passengers, but drivers will not control passengers)

 

Automatic climate control system (Backlights work but controls are unresponsive)

 

MPG computer in center screen does not register anything

 

Exterior temperature gauge

 

ECT Snow button does not work

 

Drivers seat belt warning doesn't work (passengers does)

 

Engine temp gauge remains on "C"

 

 

I keep seeing this issue online but no one ever posts the solution. 😞

All at once.
It happened about a few weeks ago but then after a few days everything went back to normal. 
Checked my fuses and they’re all fine.

im also dealing with the battery draining as well now. 🤯

Hello, Jeremy.

I suggest that you have your battery load-tested. Having lots of failures, simultaneously often points to a failing battery or bad ground connection. Make certain your battery cable connections are secure and not corroded.
