Symptoms
The cabin never gets cool on a hot day, and the back seat of a 79 dual-cab is miserable.
The fix, step by step
- Clean the condenser of dust, grass and bugs first.
- Then consider an AC amplifier such as Freezebrain, which plugs into the factory controller to lower the evaporator temperature and can add idle-up control.
Tools & part numbers
- Soft brush and hose
