That's an excellent idea.... Will do these this winter. But in my all cars ac has been working fine since last 2 years. 1988 accord, city 04, and Pajero 1990. City's ac was serviced last week for the first time in 9 years because of low blower output. Accord refill and service was done 3 years back. Pajero never some i bought that this winter.
All have been working great in Hyderabad in temperatures over 47 degrees celsius....
