Replacement 1. If the compressor is marginally operable, run the engine at idle speed, and let the air conditioning work for a few minutes, then shut the engine off. 2. Disconnect the negative (-) battery terminal.
Inspection 1. Measure the resistance between the terminals. 2. The measured resistance is not within specification, the blower resistor must be replaced. (After removing the resistor) Replacement 1.
