Re: 2007 Honda Accord - Driver's side *hot*, psngr side ice cold

It's sure looking like the problem is a faulty blend-door actuator. But before you spend the money for a new one, try the test mentioned earlier. In any event, let us know how it goes.

Re: 2007 Honda Accord - Driver's side *hot*, psngr side ice cold

I'm not an expert on Honda A/C systems. But because you're getting heated air (not just ambient air) out of the driver-side dash vent and nice cold air out of the passenger-side vent, it seems to me that the most likely cause of the problem is a faulty left-side blend-door actuator. You could test f...

Re: Citroen Dispatch - can't find leak

Good work finding the condenser leak and solving that problem. You didn't give the vehicle's year, engine size, front and rear A/C or front only, and refrigerant type. It sounds like a European-spec vehicle, although you didn't say. However if I do a vac test the gauge drops to near enough zero with...

Re: PAG Oil Max/Min System Capacity

Verified the a/c circuit was good all the way to the compressor coil which did not measure correct resistance. I decided to replace the whole compressor. That's fine, because the clutch assembly probably would have cost almost as much as the new compressor. While researching I wanted to verify that...

Re: PAG Oil Max/Min System Capacity

I'm going to backtrack and ask a few questions. You didn't mention why you replaced all the major components. Did you have a catastrophic compressor failure that sent debris through the system, or did the compressor just wear out and fail to "compress" sufficiently anymore? Was it because ...

Re: 1992 Cavalier leaking oil from back of compressor.

I forgot to mention that since you've had the system open to the atmosphere a couple of times already, now would be a good time to replace the accumulator, adding about one ounce of mineral oil to it before buttoning everything up.

Re: 1992 Cavalier leaking oil from back of compressor.

Hard to tell remotely. It could be corrosion on the mating surfaces of the compressor, the line flange, or both, preventing the sealing rings from seating properly. Maybe the line flange is bent a little from a previously over-tightened bolt, causing a slow leak, or even a bit of debris on the matin...

Re: PAG Oil Max/Min System Capacity

I'm certainly relieved that you noticed the open high-side valve in time. Otherwise, you would have had an exploding refrigerant can at some point...a very bad situation for obvious reasons. As a safety reminder, always ensure that high-side gauge-set valve is closed whenever the compressor is runni...

Re: A/C Compressor Clutch

The site sponsor doesn't list the clutch assembly online for your vehicle. But I would call Tim anyway to see whether he can locate one for you.

Re: ac tepid. accumulator hot

In reading your post, I had a similar reaction as bohica: It could be almost anything wrong. Putting aside for now the ES-12 HC refrigerant, the rebuilt R4, the OT issue, and the symptoms you mentioned, did I understand correctly that your gauge set registered a low-side positive pressure and "...
