Average Mileage: 146,857 mi (76,000 mi - 221,000 mi)


AC system leaks and/or a faulty evaporator temperature sensor can cause poor AC cooling. The failed sensor can prevent the AC compressor from coming on. Leaks cause a low refrigerant level, which reduces the ability to cool.

    I'm experiencing A/C problems very similar to that described in this post. Scheduled to take to the maintenance shop next week to have it checked. Will update upon completion.
