2007 Toyota Highlander with 2.4L engine. AC Compressor shot. Mechanic wants $900 to do complete job. Sounds about right, but I dont have the scratch. I am fairly mechanical. I know there are “tricks to the trade” with replacing AC compressors. Would anyone be able to provide “detailed” instructions or reference a “detailed” video on how to replace the compressor, crossing all the “T’s and dotting all of the “I”‘s? Thank you.
