Replacing Your Climate Control Unit in Four Easy Steps
A damaged climate control unit contributes to an extremely unpleasant ride both to the driver and the passengers. If a climate control unit is busted, the driver and passenger vents will only blow warm air even if the controls are set at the minimum temperature. This is precisely why it has to be replaced as soon as possible. As a matter of fact, you can even do the replacement all by yourself. Even the most inexperienced owner can have it installed in less than an hour. Following are four easy steps to guide you through the process.
Required skill level: Novice
Needed tools and materials
Preparing for the replacement
To get things started, park the vehicle in a safe and level place. You also need to cool the car down if it has been used previously. Once cool, pop the hood and disconnect the battery from the negative wiring.
Accessing the climate control unit
Sit on the driver's seat and locate the climate control unit at the dashboard. Pull the plastic trims surrounding the control unit. These trims have metal retaining clips. Once you pull the trims, you would also need to pull the clips out of the retaining holes. You will now have complete access to the climate control unit.
Removing the climate control unit
There will be bolts that secure the position of the climate control unit. There are usually four bolts. Using the socket and ratchet sets, remove the bolts. Once the bolts are removed, you can freely pull the faulty climate control unit out of the dashboard. However, there will be wire harnesses connected to the rear part of the climate control unit. Take note of the positions of the wire harnesses and have these unplugged from the control unit.
Installing the new climate control unit
Dispose of the old climate control unit and have the new one ready. Plug the wiring harnesses into the new climate control unit. Push it into the dashboard and secure its position using the bolts, ratchet, and socket sets. Place the plastic trim back into its place and push them into the dash. Give your new climate control unit a test.
