Valve Repair
The blend valve mixes hot and cold air in the cabin. If one side blows hot while the other is cold, the valve is usually the problem.
What's the problem?
- One side of the cabin blows hot, the other cold
- Temperature doesn't respond to the control knob
- AC works only at max cold or max hot
- Clicking noise behind the dashboard when changing temperature
