Gx 470 Ac Problems, Sulfa Type Fumes, And


Recommended Posts

Is anyone else experiencing ac blowing warm air when vehicle in idle. This problems only occurs when in idle, not when driving. I stopped another GX owner and they also had the same problem. This is a real problem when stopped in traffic in the heat of summer. Also, how about the front light burning out? We only had the vehicle about 4 months and the light burned out. Again, asked another GX owner and she had 2 lights burn out right away also! I addressed this with Lexus Western Division and they admit to the problem that the fan does not blow enough air across to cool properly but also stated that they will NOT notify all the GX owners of this so it won't become a problem until people get stuck in traffic in the heat of summer. Has anyone had a second fan put in and if did, does it work properly. I need to know BEFORE summer comes again so I am not stuck in a hot car again. If anyone has any input to this I would greatly appreciate it. I spent too much money on this vehicle to have poor air in the summer and a light burning out after only about 4 months. And from what I see, it is not just my vehicle.And what about the fumes? Anyone else with this? If so, did it get fixed??? I was told by Lexus try Chevron gas and don't accelerate too fast! Im sorry, but again, I don't want to pay this much for a vehicle to get an answer that I should use Cheveron gas. Again, thanks for any help!

TSBs are usually generated from the manufacturer. Take the TSB number to you Lexus dealer (go to the web alldata.com and print the entire list if you wish) and inquire as to what is invovled in this TSB.

Unfortuneately, getting the info from alldata requires an annual subscription.


2003 was the first year of the GX. Bugs and quirks are always worked out in the first year of use. Be patient but be persistant with Toyo/Lexus. Also do a search of TSBs for the 2003 4Runner as it is a similar platform vehicle. You may find some similarities in problems.

oops, forgot your link.
