okay to start off, I have an 97 es300 with 163k on it, My battery hasnt died yet, but, the 1st problem with the seat memory is an issue I face. It may be disconnected or just got to the point where it jsut quit. The battery could have sent too much of a current to the seat memory causing a fuse to burn out. I am not sure if there is a fuse for this, but I will investigate this and return an answer if i find the problem on mine. The Fan issue your experience is common, sometimes these things just occur. but i will talk with someone at wwork about it, and maybe I can find an answer for this.
Thanks for the response.
I rechecked the fuse panel inside the dash and everything was okay. What I didnt check the first time was the large fuse panel next to the battery. All the fuses were okay, but Fuse 10 (a/c, power seat) must have been loose because when I put it back in, the Drivers power seat memory now works. No more adjusting the seat after my wife drives :)
It did not fix the Auto Climate Control. What I did test was when I turn the temp to the coldest setting (COLD) then the fan does engage. When it is off this setting it does not engage.
Any further help with this would be greatly appreciated!
