Good point and I'll get the pressure checked. The AC does work quite good in South Florida but it could be on the teeter edge that it needs some R134a.
 
But what you are saying that since the low pressure switch cuts out the AC clutch, it also cuts out (to the computer) the idle speed control and the AC fan?
 
I've had this happen on other cars, as the low pressure switch cuts out the clutch, the low pressure side slowly build up some pressure and the clutch kicks in again and this on/off cycle continues. Usually, the idle and fans still operate as if the AC was on and working 100%.

If the climate control ECU "senses" that the compressor cannot be run due to low refrigerant then why would it go ahead and open the throttle further, and activate the fans, for an additional load that isn't there.
 
The blinking A/C light typically means the ECU is trying to run the compressor but the clutch or the drive belt is slipping. In that case the ECU would initially go ahead and open the throttle and turn on the fans as the expectation was that the compressor is operational.
 
Did you say the engine stalled when the A/C was switched on..??

As far as I know, all Highlander have brake indicators (unless somebody has removed them). ". . . he described the wear as basically being metal on metal . . ." is almost word for word what the service rep in Florida told me. I guess it is part of their script. Also, the worst thing "metal on metal" would do is to damage the rotors . . . which they want to change anyway. It is easy to look through gaps in the calipers to see how much pad is left. With some wheels it might be easier with the wheel removed.
 
The economy is bad and dealers aren't making money selling new cars. Service departments are their cash cow. It certainly shouldn't hurt anything (but your pocketbook) to change the pads early, but it makes me nervous when service reps don't tell the truth. I am going to start checking everything they tell me from now on.

My 05' Highlander has 70,000 miles and finally needs the front brake pads replaced. The dealer has bumped their repair rates recently because I suspect it is the only way they can stay in business since they are not selling too many cars. I'm considering going to Brake Check, Just Brakes, Brake Specialists, or some other brake repalcement company, but I am afraid I will get sub-standard brake pads that will squeel. Has anyone had any good experiences replacing brake pads at any aftermarket company? If so, I need your advice and wisdom. THANKS!

On front brakes I had dealer do them, they are better at rsurf. the rotors. Ask the other places what kind of pads they sell; go to Auto parts stores price out different pads see what the dealer sell as well. I have never had a problem with the dealer installed pads. I know the dealer charges more but they know Toyotas.

I know that Just Brakes are the worst of the worst, $99 for all 4 wheels advertised to get you in the door, then all kinds of add-ons, stay away from them.

IMHO, there is rarely a need to resurface rotors at the first brake pad change, unless the pads have worn to metal, before which you would certainly notice the "squealers" (worn brake pad indicators). The HL is the easiest brake pad change I've ever done, nice design.
 
My 2001 still had pad thickness over the wear limit, which IIRC is only 1 mm, at ~60,000 miles when I replaced them because the VA safety inspectors were worried about them lasting another year.
 
Costs - I get coupons from three competing Toyota dealers, and there is almost always an active 25% off parts special going on, which makes original equipment competitive with discount stores, and original equipment is almost always better quality.
 
If your servicer recommends resurfacing or replacement of rotors, ask why - look at the surfaces of the rotors if possible. They don't need to be glass smooth, new pads will bed in quickly to minor irregularities in the surface. The only reason to replace rotors is if they have worn too thin (or they somehow have huge gouges), and the shop should show you a measurement, and refer to a service limit. HL pads are not very aggressive, and shouldn't wear rotors to replacement by the first pad change (or the second).

Thanks for the input. They must learn the "metal on metal" phrase at training school. This is not the only questionable work that has been done on our vehicles in the last year by my dealer's service department. I guess it's time to start having an independent shop do the routine maintenance.

"..if they have worn too thin.."
 
In my expereince brake rotors do not "wear" too thin, only being turned on a lathe results in the rotors being too thin to be turned yet again.

I agree, I think most times rotors need resurfacing to reduce any warping or glazing that occurs with overheating them, or heating them up too quickly,
