#10 of 48 Tranny slipping out of OD by movinonout Dec 05, 2007 (6:09 pm)
I have a 91 LS 400....running great, but I have a small issue I need answers to. When I apply the brakes the reverse light indicator on the dash lights up. Also, the car automatically downshifts as soon as the brakes are applied. I think it is electrical posibly to do with anti-lock brakes. Brake lights and reverse lights operate perfectly but, just wanted to see if anyone knows how to fix this problem   Look for a wire bundle on the drivers side trunk hinge that flexes and breaks. this cause your reverse indicator to light up when the brake is applied and also feels like the transmission is disconecting or downshifting. Fix that wire, and your car will not jerk anymore when touching the brake.   movinonout Replies to this message: rhoule (Jan 07, 2008 5:15 pm) vguthrie (Apr 18, 2008 6:56 pm)

Replying to: movinonout (Dec 05, 2007 6:09 pm) Thanks for the wire bundle recommendation. I have a similar proble with my warning light that a bulb is burned out when there is none. Now when I apply the brakes the reverse light goes own and the transmission downshifts and the panel light goes completely off or flickers. Something is shorting out badly and hopefully it is only in the trunk.
#12 of 48 Lights all over the dash... by bluesind Jan 11, 2008 (8:18 pm)
I have developed a problem with my 1992 LS 400. The battery seems to have been in a bad state, slow to start, sometimes needing two or three tries to turn over (this happened over several months). Toward the end, all the warning lights on the dash came on - radiator, battery, oil - the whole shebang. The battery was so low while going down the road that the radio only worked while the heater was off!   I replaced the battery and the car starts fine now - but all the warning lights (as mentioned) stay on. What could this be - and what needs replacing?   JL Dallas TX Replies to this message: j7wild (May 10, 2008 5:02 pm)
#13 of 48 Side View Mirror by ckennedy Jan 25, 2008 (5:41 am)
My passenger side view mirror on my 2001 LS 430 does not retract fully when I shut the car off but will extend out completely when I start the car. The driver side works fine. The mirror stuck another vehicle while driving a ways back according to my wife. Any ideas as to what is involved? Is this a dealer or regular mechanic issue?
#14 of 48 problem with electronics...please help! by brem15 Feb 19, 2008 (10:50 am)
I left my lights on the other day and when I tried to start my car, the battery was dead. What is strange is that the first time I tried to start my car, nothing electronic worked. The steering wheel didn't come out and nothing else worked. However, when I went out later the lights came on when i opened the door and the steering wheel came out like usual, but the battery was still pretty dead.     I hooked up a charger and let the car charge for a while and the car started right up, but nothing electric worked. The steering didn't come out, the dashboard didn't light up, the windshield wipers didn't move. I checked a few of the fuses and changed the interior dome fuse and now the interior lights work, but the dashboard doesn't work and I checked to make sure that the dashboard fuse is ok and it is. What could be the problem. I obviously need electronics. Also, I had a garage check the batter and they said that it was ok, not great, but fine.   Also, once the car was started I tried to put it in gear and the gear shifter was locked. I pressed the Shift Override button or something, but nothing helped.   Thank you for your help.   Josh Springfield, IL
