When I activate the drivers window the left and right back seat windows as well as front passenger seats go down at various times.

The codes that appear are B1421 and B1422. I believe that code B1422 is for the solar sensor on the dash and I would like to disable it. Thanks

2003 rx300 awd with abs,vsc,trac

But could also be behind centre console. Previous owner had glovebox taken out and a servo motor; heater, replaced by Lexus.
Sounds like CD player running through all the discs. Its intermittent. Doesn't seem to matter whether the A/C is on or not. Haven't had heater on yet because it's hot here. Wondered whether the servo might be ok, just responding to a miswired signal or a short. What do you think?

At first, it was only one door that would not lock or unlock using the remote entry or the power lock button. Now, all of the doors have to be manually locked and unlocked.

I have to undo battery cable to shut everything off. What is causing this?


Performed 1/9/2013 "Ck engine light on,running rough (ex wife had vehicle then) Codes P1150, P1155. Air/fule sensor failed replaced sensor $319.63 (this was front sensor). 2 coil packs have failed replaced coil packs and spark plug" $561.20 Total $966.71

6/4/2014 Got vehicle in divorce. Set in drive for a while-tried to crank ponce a week. Ck engine light came on-running rough (bogging down esp on first few miles but sporadic now). Same shop put in BG44 fuel system cleaner and had me run two tanks of gas (never anything but premium since day 1). No help.

6/20/2014 Took back "several codes P1130 and P 1133 came back on, 02 rear sensor failure replaced" $322.67
"had a couple of misfire codes. may need coils later on. will need third 02 sensor"

I have had my car in for repairs for over a month now, I pick it up and another light comes on, usually the service engine light and the VSC light. It does affect my mpg. I have now spent over $1700 and have replaced the front oxygen sensor, downstream oxygen sensor and both knock sensors.... What the heck? If the lights come back on again, then what??

I think the stabilizer rod, bushing is shot.

Losing power hard acceleration

My VSC and Check Engine lights have come back on, which has happened a lot in the 10 years I've owned the vehicle, usually after getting gas, etc. I'm now getting the Check Engine light blinking if I go anywhere near 60/3rd gear, and exhaust smells at times, with the acceleration seeming to slowing down, or reluctance to accelerate. I've had my wiring replaced a couple times due to the car not wanting to turn over or, if turned over, not accelerating/jerking. I've also gotten a new alternator/battery.

i have problem with abs beacuse fuze was blone i replace that since than car is not stoping way is sappose to be is skiddind than stop after i check tire brake senser is looking fine what else can be a problem

Fuses are all good but no power to panel fuse or brake light fuse directly above it! wires seem to be fine. After about 20 miles starts to idol ruff and will not exhilarate to highway speeds!

how much to replace rear main oil seal

it shifts ok for a few miles

it is a squeaky noise and after the air gets sucked in it stops

lock door function will not work electronically and
lock button will only work manually
can exit the car only if I click the unlock on the key or the unlock button manually

further usually now if I open the door and click the lock function and close the door, the doors will lock electronically , but after I walk a few feet half the time the alarm will go off
if I then click the unlock button on the key and then the lock button the alarm will stop , relock and stay locked

both a Toyota and Lexus mechanic have examined it and are stymied
the Lexus mechanic guessed that the driver door mechanism must be replaced, but 2 tests he asked me didn't work
1. when alarm goes off look to see if red door button switches back and forth and 2.listen for a clicking/unclicking sound comes from the driver's door

neither ever happened


I have a lexus 2000 rx 300 that has trouble code 1354 I have a check engine light on that blinks on and off from time to time. the Trac light also comes on after the car is warmed up The car had been running fine. Now, it smells like gasoline, especially noticable when I start it. It runs a little rough at idle. It also has developed a problem with shifting. What I would call "third to fourth gear"; what I notice is that as it speeds past 40 MPH and then to 50 MPH, it should shift, but it doesn't. It acts like it's in L2, but it's in D and the overdrive is ON. If I take the OD OFF, it doesn't change anything. any ideas what the problem can be

when am driving and want to apply brake i hear a brake warning and when i continue accelerating it stops.continue in that process as i try to apply again.

Plus the car is riding rough when cold. I did change the gas cap but now it is on so tight that I have to use plyers to remove

T1155 2002 rx300 thank you

codes reveal misfires on 3,4,and 5. In addition, periodically, the brakes do not stop the car. They slow it down, but after one depression the pedal becomes extremely hard, like pushing on a rock, and does nothing to help stop the car. Can these issues be related? (It has been extremely cold outside.)

plus rpm lower than normal

this problem would just start sometimes at kick-starting the engine or inbetween motion, whenever I take my leg off the accelerator.

My car seems running fine. but sometimes (two three times a week) it makes noise (seems like something is holding it to go forward from full stop) when I press gas paddle after releasing the brake while driving. I have recently changed all brakes, rotors, brake fluid tube and calipers but the problem still exist. I have 145000 miles on the car and never did tune up since bought. Any help will be appreciated.

I used synthetic oil from the begining never had excessive oil consumption issues. Changing oil every 5K miles. Current milage 240K

We buy new battery, when we park the car, the next day, it has to be jumped, starts easily, seems to be a slow power drain? When switched on, the parking/brake? lights (the round smaller ones on the end of the front grill) seems to be on and won't cut off. What should we do?
