Question about 1999 Lexus Gs 300
All the lights for air conditioning stopped working, the cig lighter doesnt work, the clock doesnt work and it is stuck in park. We found the little button next to the shifter and it will switch to reverse and everything if you manually hold down the button and shift it to drive and stuff. But is it a fuse that i need to replace to get the automatic shifting to work again or what? Its a 99 lexus gs300.

hello freddy - the good news is that your lexus has a self diagnosis system built into it. this is what you need to do.
drive to an auto zone or similar autoparts store and have them put your lexus on their computer to scan for trouble codes. they offer this as a free service. with a little luck this scan will isolate the problem and the fix will be quick and easy.
if this doesnt fix it for you get back and let me know what codes popped up.
here is a link to the lexus trouble codes so you will have added insight. good luck.

chances are you don't have to replace the computer. the reason i tell you this is because you did not mention that the car is running lousy. no complaints of rough idle or missfire or hard starting. chances are that your engine speed sensor which sends the signal to the computer which then controls the transmission is most likely the culprit.. and it could just bhe that there is a loose connection between the two. if that is ok then your transmission control module is faulty. this is not the main computer, but the gobetween the trans and the ecm.. hope this helps please rate this...thanks(btw....the knock sensors control timing not the trans mission)

If the transmission "brain" in modern cars senses problems it can keep the tranny from shifting. Usually leaves you in second gear as a safety and warning indication. I don't now if that year lexus had this ability but getting it checked on a diagnostic computer that read transmission codes should shed some light on your situation.

Sounds like you need to reset the auto up/down feature. Most vehicles require you to "roll" the window down, hold for 10 secs, roll the window up, and hold switch for 10 secs. This should reset it. If not, you may need to do reverse of what I said.
