Last fall on hot days my AC did not completly cool the car. When I visited the mechanic he told me some bull that it would cost $600 to repair the AC on my car.
I waited till this spring and things did not change much. This tells me that the r-134a FREON was low but did not go any lower in the last 6 months. So I decieded to do my own repairs.
I went down to Plattsburg and picked up a can of r-134a FREON at WALMART for $19.44. All you have to do is connect the snap on hose to the AC system and check the gauge to see if your FREON is low. If it is you add some with the can of FREON refrigerant supplied. It has now been about a week, an my AC seems to be fine.
If you are interested in going down to pick up a can of FREON at Plattsburg. It is about an hour from the Champlain bridge. Just take Highway 15 south to the border. The road on the American side is 87 south. Go along the highway and do not go into Plattsburg till you see a Sears. That will be the shopping area for all the other major stores in the area. Walmart is just across the road from the Sears store. I went early in the day and there was a 6 to 10 car wait at the border, when I was coming back at about 2:00 there were no cars waiting to get through. I suggest you go for a mid-day trip, if you cross to the US at about 10:30 a.m. and expect to cross back at the border at about 2:30 p.m. you should not have to wait to cross.
One thing that you should all know is that you can get AC refill kits here in Montreal at auto parts store, but it is not the original r-134a refrigerant, it is actualy butane. I prefer not to use this as it may be very dangerous to have a compressed explosive gas in your car. Remember that part of the air conditioning system is inside the passenger compartment under your dash. Should it have a leak and a spark hits the gas, the outcome would not be good.
I hope this information helps anyone with an AC problem.
P.S. I am not cheap, I just prefer to spend my money on other things
I also have suspicions that the rat bastard mechanic let some of my freon out of my AC system when he was servicing my car for other things. So, gents. save your money for the MPs and SPs, and for all the rat bastard mechanics, a greasy garage broom handle up their theiving arses!
