Are you having problems with a vehicle you just bought?
Many people that I know are complaining about the HVAC problems that Columbia used cars are having this year. I have actually talked to several mechanics and they said they have seen a major increase in heating and cooling problems among the used vehicles being sold. One of the mechanics said that they are having to replace water pumps on several cars weekly that was just purchased. It is not only water pumps that are having to be replaced, entire heating and air conditioning systems are breaking very shortly after the customer buys the vehicle.
The reason that you should do a thorough check on any truck, SUV or cars HVAC system before you buy it is very simple actually. That reason is If you buy something used it will most likely not be covered under warranty. This means that if the AC or heating system does break and stop working you will be fully responsible to fix it. That includes you having to pay for the repairs out of your own pocket.
