My local garage owner said my 2007 ls460 was made by TOYOTA! the cheeky blighter! I was most upset.

Margaret (my better half) said he was only jealous because he is an uneducated oik! she's bonkers!

Help!

my abs is activating everytime just before i come to a stop, wet or dry doesn't seem to matter. I have no abs fault light on, is my ecu shot? brakes are all new and have checked all sensor pick-up rotors. The severity of "buzz" throught the pedal increases along with braking force.

any ideas?????????

oops! 1996 ls 400

LOve the profile pic, pretty funny.

My hitler impression :P

First pic now in album!

My series 1 GS300 has a problem with it's AC. It switches on fine but then only runs for 10 seconds before disengaging the compressor. It then stays off for 30-40 seconds and then starts again, but only for the same 10 seconds. It keeps on doing this in the same cycling pattern.

Lexus looked at it today and re-gassed it as they said there was some air in the system but drove 30 miles after and problem remains. I don't think they have the ability to diagnose. Before I took it to Lexus I got Kwik-Fit to re-gas the system so I am confident that gas is not the problem.

As the compressor engages and does it's job i.e. it cools the air very well, my guess is that it may be a faulty sensor telling the compressor to switch off prematurely. This only a guess as I don't pretend to know about this aspect of cars, although I am somewhat interested in mechanicals in general. Hate cars with sensors all over the place. They can ruin a good car.

Am at a bit of a loss. If Lexus can't help, where else do I go? Changed the AC relay just to eliminate it and it is not faulty.

If anybody can shed some light I would be most grateful.

Regards to all.

I assume by "disengage" you mean the engine revs drop off back to around 600ish then theres a pause before it starts pick up to the revs for when the air con cuts in. There is a sensor actually on the aircon compressor but it would be a bit of a trial and error swap to find the fault as i don't know the aircon circuit.

If you look here theres a few diagrams may give you some clues http://www.toyodiy.com/parts/p_E_1995_LEXU...QFW_8719.2.html

Thanks for the reply, I will try and analyse with help of a friend with a brain. Regards.

Sounds like you got yourself a leak somewhere, the low pressure switch is cutting the power to the compressor clutch to protect it, after a while once the high and low side pressure equalises the switch comes back in and allows operation of the compressor albeit temporarily, NO a/c systems require recharging as a service the refrigerant Never wears out just escapes!

Air in the system??? theyre full of sh*t air in any a/c system is certain death! your system needs pressure testing and a leak test carried out , once you have located the leak and sorted it then you can vac it out and recharge to the correct amount.

Hope this helps,

good luck!

Hello all,

got my first gs this week, its a 2003 300 and i have to say i very impresed with it. Previously have had a few soarers (incl the active!) but none can even compare to this so called middle lexus. In my opinion the interior on this car is so much better than anything else. Had to put new discs and pads on today and what an unusual luxury to be able to buy parts off the shelf! In my garage waiting for the right car is a brand new set of latest edition IS 17" wheels with original dunlop sportmaxx tyres mmmmmm....... will post pics tomorrow.

excellent site by the way.

I'm aircon engineer by trade so if i can be of any use to any of you let me know. :D
