How long does it take for all of the computers on automobile data busses to fall asleep when the engine is turned off, doors closed, all accessories off, etc.? The usual answer is 15-30 minutes. That answer is important. If the battery is running down to a no-start, and you’re doing a test for parasitic current draw, you don’t want to test the vehicle before all the computers have powered down, so the reading is hopefully in the under 40 milliamp range. Otherwise, you could condemn a perfectly good module.
When having your mobile A/C system professionally serviced, insist on proper repair procedures and quality replacement parts. Insist on recovery and recycling so that refrigerant can be reused and not released into the atmosphere.
