4Runner AC DIY Repair

The 4Runner’s AC had a slow leak and wouldn’t blow cold air. Toby ignored it for a long time (lucky to own another car with working AC). But with instructor’s help, diagnostic equipment, and parts at cost, it was time to fix it.

Hooked up to the a/c system tester, and filled with fresh florescent dye, Toby’s instructor Aaron found a tiny small leak near the a/c receiver drier.

Replacement parts were ordered. R&R was a breeze. The a/c condenser (with the leaking drier) drop out in one unit, without needing to remove fan, transmission cooler or radiator. Great job, Toyota!

Hooked back up to the system tester, refilled the system and passed with flying colors!
