It worked for my sisters '95 Runner. About 3 yrs ago she was having a hell of time getting it to cool down on hot days, it was only slightly cooler with the A/C on on a 100+ day then with the windows down, but definately not comfy, where as the summer before it had no problems. On visual inspection everything looked good and clean, and everything sounded good as well, the system pressure was also good. The shop recommended before replacing anythin(thus having to open the system), try replacing the old R134 with new(I am not sure if they recommended this just to get more mnoney, or actually new it worked). It seemed a little bogus to me since the A/C system is a closed system and nothing gets in, however changing it out seemed to do the trick. It might be worth a try before replacing expensive pieces. An A/C shop should be able to do all of the work for you, you definately want the to reclaim the R134, it is toxic in both long/short term exposure.
