#5372 of 5646 2007 Camry A/C won't start
Apr 19, 2011 (8:42 am)
I just noticed the a/c on my 2007 V6 LE won't cool. The light on the dash comes on but there is no sign of compressor activity.The relay seems to work when tested on the bench but there doesn't seem to be power heading to the relay from the controls. Also, when I bypass the relay, the compressor clicks but doesn't sound like it is starting. I'm thinking possible freon leak or possibly seized compressor. All of which sounds pricey for a 4 yr old car from Toyota. Anybody have experience with this? Thanks.

This can happen when the cabin air filter gets too dirty...

I can't pull out the service manuals since I'm travelling , but I would suspect low freon pressure.
Many A/C systems have a freon pressure switch as part of the system, and if you don't have enough pressure then the compressor is prevented from turning on. Theory being, the freon has oil in it, and if there isn't enough freon....then there is not enough oil for the compressor, and this prevents compressor damage.

Low freon pressure means a leak. Unfortunately leaky AC is something that most DIYers including myself can't handle properly. Check for AC electrical and control problem and go to see a mechanic. Even small piece of flying road debris can make pretty impressive damage to evaporator and your pocket.

Ok so now it's about a month later and guess what...another coil error. It is a 6 cylinder and this is replacement number 3. Something must be causing this to happen...I just can't believe that they are all going bad one at a time within a month of one another. Someone must have some insight. Please give me some suggestions...I don't want to get another car but I can't afford to keep taking it in for the same problem. Could there be a short somewhere? I don't know what to do next. Is it worth paying extra to have the last three replaced while the have the manifold off to replace this one? Any suggestions would be greatly appreciated. Thanks

Can you have sombody reset the codes. Sometimes Auto zone can be talked in to it. I was wondering do you have a remote start. I'm wondering if you try to start the car by mistake while the car is running it might cause a electrical surge to the coils.
When my coil went bad it was right after I made that starting mistake though I was told by many that should not have been the problem.
I hope others can this sight can help.
I also think Toyota is using less than quality parts these days.

Who is diagnosing this problem, and what error codes are you getting? It would be very unusual to have all these coils going out.
I've found that random misfire across multiple cylinders, could be fuel delivery or one of the many sensors (like crank). A solid error code on only one cylinder, would suspect either the coil or plug in that cylinder.

No I don't have a remote start so that isn't it. I am at a loss...any other suggestions? Anyone?

Thanks for the input we will see what the outcome is in a few days...as back to the dealership I go. I like having suggestions to give them when I go in so they can have something to go on and try to fix the real cause of this problem instead of just replacing parts one by one.

Any new info on the ignition coils
