CUMan is right. It's your expansion valve. I drive a 94 es300 and mine did the same a few summers ago and I thought it was the refrigerant getting low but my valve was sticking. If a/c is important to you then better get it fixed before summer starts. Cost me around $500.

I need help finding a good lexus shop/mechanic in the dayton ohio area. I've got a '94 ES300 that im needing to get some major work done to. I know there's a Lexus of Dayton near me but I'd like to find an independent shop before I pay dealership costs. I've been using Champion Auto Service in Dayton and so far they've done a good job. I'd just rather use a dealership that specializes in Lexus. Any ideas/suggestions?

Check the brake pedal switch that turns on the brake lights, it may be adjusted just a little too critically, "hair-trigger" one might say. Also ALL your rear brake lights must be functional, including high mounted one, or the cruise control will sometime be intermittent. You cannot use LL, Long Life, type bulbs nor LEDs in those sockets without compromising the cruise control's "brake-on" monitoring cutoff circuit. well it sounds about right because i just had my master cylinder replaced (see my other thread) and the brake pedal is hairpin trigger like now....the other thing i did put in were those long life bulbs but i havent had the cruise control cut off until i got the new MC. i'm actually glad it isnt broken but i had to drive 250 miles with my foot workin the gas pedal. good excersize but very unconvienient(keeps you awake though) :P . so is this something to just ride out or do i need to get it fixed?

i drive a 94 es300 about 193k and coming back from tennessee i had the cruise control on and all of a sudden it cut off and the cruise light started blinking then went out. i tried to turn it back on several times but it wouldnt turn on....well after my fuel stop i tried turning it on again and it worked. i turned it on and off several times to make sure it was working and no problems. has anyone else experienced this? my thoughts were that something in the programming was confused and cut it off then when i turned my car off to fuel up it resetted itself when i started the car back up...or maybe it was just some phantom car problem that happens sometimes....i really dont know P.S. 441.7mi@15.742gal=28.1mpg on 89 shell gas

you were right it was the master cylinder.......i took my lexus down to memphis tennessee for 3 weeks and drove it down there with the pedal that way.....well one day i hop in my car and start down the road and i go to press the brake and NO BRAKES AT ALL!!!! i had to use my e-brake to stop the car but luckily i had the green light and was able to pull over to a parking lot. i know if the cops woulda seen me they woulda thought i had just robbed a bank the way i was hopping up onto the curb so i wouldnt hit anyone....needless to say it was bad....VERY BAD. i finally took it to a little shop near where i was staying down there and they put on a remanufactured master cylinder but then called me sayin i was having a problem with my proportional valve. well they put another one on and said they were having the same problem but just 2 of my brakes were working....well finally they put on a NEW master cylinder and all 4 brakes now work. i barely put my foot on the brake pedal and the brakes bite hard. one of the pple i was staying with while i was down there was an ASE mechanic and he said the problem they probably had with the proportional valve was that they bled the brakes too fast and caused it to shift over to one side and when they finally realized what they were doing wrong they already ran through the 2 master cylinders(something close to that anyway). cost me $390.10 for the new cylinder and labor. but to everyone thats having this problem....take the advice of GBHRPS and change your MC NOW! i was fortunate but the next person may not be. Thanks

yeah you should be able to...the device to look for is called a line converter....you can get one at your local best buy, circuit city, or any car audio place. just tell them you want to hook up an amp to your factory stereo and they should be able to help you out.

i own a 94 es300 with about 190k mi. when i bought the car the brake pedal at first had some feel to it when i pressed on the pedal (spongy) but then it would go all the way down to the floor....i called up lexus and got an estimate for replacing rotors and pads and called Sears. Well, i had Sears do my brakes for the lower price and after that the problem improved. Well 2 weeks later i took the car to a local garage to have them replace the pads and rotors on the back and bleed my brakes to see if that would help. They said there was no air in the lines and that i would need a new master cylinder and that's why the brakes feel the way they do. well a couple weeks later i park the car one night and the next morning my bro uses the car and calls me sayin the pedal has to touch the floor for the car to stop. i get in the car and coming to a stop light the pedal has no more feel and i had to press the pedal all the way to the floor. Now i have to press the pedal to the floor to make the car stop and not only that, but when i do that i can feel the car pull to the right. Sometimes if i press the brake pedal hard it will act as it should but with normal pressing it goes to the floor. So is the obvious reason the master cylinder or could it be something else? And also if i keep driving and using the brakes like this for about 2 or 3 months is it going to damage anything with the brakes or car.....Thanks.
