Re: Seeking help with my Lexus/Toyota A/c

Absolutely. If you are finding bits of foam coming through the vents, something is failing.

Mitchell DIY subscription is $20 for a one month access. You get the whole factory service manual.

Well worth the price, you can save days of work on jobs like removing the a/c evaporator box.

Re: 2002 Pontiac Ram Air Trans Am ac is not cooling properly

Ask yourself, how did the debris get all the way to the radiator? Through the condenser? Or around it somehow? And A19 has a valid point. I have seen condensers clogged with gnats, while the surface is clean. I always recommend deep cleaning the fins with a strong surfactant like simple green, spray...

Re: 2002 Pontiac Ram Air Trans Am ac is not cooling properly

That is an ongoing problem with electric fans. No real metrics for the OEM motors, and aftermarket stuff is all over the place. Usually the difference between ram air & parked cooling is a good indicator. Duct taping the gauge set on the windshield on the passenger side & going for a drive w...

Re: 2002 Pontiac Ram Air Trans Am ac is not cooling properly

Sorry Danny. After a19 starts clogging up a thread with useless junk I just scroll to the end - where I see pressures as high as 400 psi. I missed the part where you sprayed the condenser. You say the fan blows well. But what is well? is it 75% of what it did when brand new? The only metric we have ...

Re: 2002 Pontiac Ram Air Trans Am ac is not cooling properly

18 year old electric fans. You are chasing your tail. Spray the condenser with water and watch the pressures. You should be able to get the system to stabilize at the control valve pressure on the low side - if you can get rid of the heat. We went through this at length on the old board. The electri...

Good luck in your search. As others have said, avoid tire shops - and any place adjacent to a junk yard.

Re: 2007 Ford AC low side cycling

If that FS18 drags the 4.6 down when cycling you are pushing your luck. Grab the clutch plate on the compressor & turn it by hand. If it is gritty or notchy you have some parts to replace. Running it with 60f vents at idle means it is really low on charge. Driving it like that keeps it from retu...

Re: Help me diagnose my AC

Your mechanical fan clutch is shot. The mechanical fan is the most powerful air mover under the hood. The electric fan is an add-on to help in extreme conditions and with the A/C. Again, Jeep has changed the aux electric fan operating parameters several times over the years. Some are supposed to com...

Re: Help me diagnose my AC

Does this vehicle have a mechanical fan and an electric fan, or only an electric fan?

Jeep has changed the fan configuration too many times to count.
