My base 16 Trax has always been weak on the A/C side. I found that opening the windows for a minute or two works better than just jumping and expecting it to work like a '66 New Yorker A/C. After it get cooled down to outside temp, turn it on and place it on recirculate. It you do that it works better because it does not have to cool as much of the warmer outside air. But you got to remember that 1. 4L gets 37 mpg for a reason. The A/C off a New Yorker would use 25% of the available hp in a Trax just to run the A/C. That is if you some how could make it fit. That monster had a 440 in it for a reason and it did not need to shut off A/C when you put the pedal to the metal to pass. The En ghen ears are looking for minimum HP solutions for mileage. If you don't have your foot in the throttle to the max, it don't need massive boost and cubes to keep it moving. My brother had a Honda motorcycle that had a bigger engine and two more cylinders. If it was 115 outside you did not run the New Yorker on Max cool for very long, unless you had a winter coat on.

Two comments/warnings. overfilling is just as bad as underfilling. Look at the pressures on both the low side and high side of the A/C circuit, and decide if you're truly low. The web will give you in-spec numbers for both sides for your car, and they change Slightly if the outside air temp changes. so watch for this. Maybe 35-45 psi on the low side, and maybe 160-200 psi on the high side. And 2) some cars only have an air-flapper valve on the car's heater core, to open ( for heat) and close (no heat) the cabin. BUT. radiater fluid may still run thru the heater core. For some cars (like my Scion xA, I ADDED an in-line valve on the heater line going into the firewall. Have it closed in the summer months, and open in the winter. So for the summer, not only is the air-flapper valve closed, but so is any liquid radiator coolant flow to the heater core. Made at least a 10 degree change to the cabin air flow temp (colder.

Hey Scotty, I have a '06 5. 7L Hemi Jeep Grand Cherokee with about 174, 000 miles on it. I've owned the vehicle for the past 40, 000 miles. Other than routine maintenance, I haven't needed any outrageous repairs on it. I'm just curious to know what you think of the vehicle and how much life you think I might have left in it. Considering it was built prior to Chrysler merging with Fiat, I comfortably assume it'll last longer than most modern Jeeps. I use it as my daily driver, and drive cross country at least twice a year from MD to MT.

Scotty I have a 2005 Toyota Camry xle 2. 4l 4cylinder. That the engine stutters when the AC compressor/electric radiator fans kick on. This only happens when the car is sitting idle like at a stop light for example. Going down the road at normal to high speeds it doesn't give me any issues only at idle. I have replaced the air filter in it last month I put in new laser NGK iredeam spark plugs in an effort to solve this issue. But no luck It has 260, 000 miles on it. Any ideas what could cause this.

On another note, don't discount how much a clogged cabin filter can impede air flow and make the ac not work as well (or, more specifically, not be delivered as well. When I got my Sentra, the ac seemed to struggle on the hottest days to keep the cabin cool. It was later when I checked the cabin filter that I discovered a mess of old leaves, pine needles and about 75% blockage of the air flow. Cleared that out and now the ac output will freeze you to your core.

Scotty whey the temperature gets above 110 degrees here in Arizona, when my car is parked and idle after 5 minutes, the A/C compressor On and Off, on and off simultaneously. Thats only in temperature above 110 if its below 110 like 108 and below it works fine. Also while driving on highway, it works when above 110 but the problem is when its idling. Is it normal or could there be a problem? 2013 forester. Freon added and condenser cleaned but problem still persists.

My father in law told me his dad worked for Boeing in the 50s. They had a power plant outage after he had retired and they asked if he could come in and fix it, he could charge what he wanted. So he went in and went to the control room and smacked a spot in the wall, everything turned on. Sent them a bill for 20k. They asked for an itemized bill so he sent them one. Smacking wall 1, knowing where to smack 19, 999.

hi Scotty, I have a problem with AC on my Honda Civic 2013. When I set AC to recirculate I start getting some what sweetish, chemical smell that last for only a second or so and then stops, after some time again goes for a second and stops (feels like when the compressor kicks in. What could it be? That problem persists since I bought the car with 5k miles, now I have 40k. Thanks

Don't buy an aftermarket digital AC control unit if you have an older vehicle with regular switches. They typically die after a few months, right after the season changes, and you won't even know until next year. Also, don't forget to hit the recirculation button (many older systems do not remember it was activated last time the car was on) THAT'S how to get it twice as cold.
