Toyota corolla 2005 ac blows cold on high revs
I recently purchased Toyota Corolla 2005 japanese made automatic transmission with 150000 kms on it.
My car ac only works when I drive on high speed or accelerate. I tried to fill the freon but all in vain. The ac mechanic told me its compressor is weak bcoz low side shows high psi. Btw this is the my third car the ac mechanic unable to repair despite changing with scrap compressor. I had to sell my previous cars having the same issue.
There is no code, no leakage anywhere too. Besides I never saw the car dripping condensation water too.
I love the car but I cant drive without ac as I live in a very hot area.
Running pressure checked with manifold are
40 psi on low side
140 psi on high side
46*C . Humidity 10%
You might also try diagnosis by checking temperature at various points in the AC system.
