The air conditioning display on a C5 Corvette is known as a Climate Control Panel or Climate Control Module interchangeably. This module houses all the computerized control and operating software to carry out your automatic climate control functions. A very common problem with the air conditioning displays on these Corvettes is that they either display dimly, sometimes sections are dim, they don't display at all, or they don't function at all. Any of these problems may be constant or intermittent. Some C5 Corvette owners have reported that when these problems occur hitting bumps in the road or tapping the climate control panel may cause the symptoms to worsen or improve.

Blank Climate Control Display C5 Corvette

The image above is of the automatic climate control module for a C5 Corvette. If your module looks like this one and has a blank display while installed in the car and turned on you may be wondering what could be wrong.

Overwhelmingly, these problems are caused by faulty solder joints for power supply resistors on the module's internal circuit board. In the past it was popular to simply replace these modules and few repair shops like ours existed that knew how to repair them. Now they have been discontinued and this repair service is growing in popularity. Why should you choose us?

Position Gear Selector and Brake Lever

  • Position the gear selector as far rearward as possible
  • Pull the parking brake lever up

Remove Temperature Sensor Cover

  • Remove the cover for the inside air temperature sensor
  • The cover is simply snapped in place they are easy to brake the tabs on so be gentle

Remove Screw Beside Cigarette Lighter

  • There are two screws behind the door for the ashtray and cigarette lighter
  • One is to the left of the cigarette lighter
  • Like the previous screw it is also T15

Remove the Radio Bezel

  • With the console door closed, the gear selector back, and the parking brake lever up remove the radio bezel
  • There are still tabs holding the bezel to the instrument panel, pull rearward to disengage the tabs
  • The steering wheel may need to re-positioned to find the right angle to extract the bezel
  • Watch the bottom of the bezel as it passes over the leather top of the console door.
  • On coupes I prefer to pass the bezel over the console with the door closed to avoid potential damage to the door mechanism.
  • On convertibles I prefer to pass the bezel by an open console door as there is less room due to the body colored waterfall.

Prep the Joints with Flux

  • We use common rosin flux to prep the joints and clean the solder and prevent oxidation as we re-flow the joints
Radio Shack Rosin Flux

Prep the Resistors with Flux

  • Apply a dab of flux to all the solder joints of the resistors

Re-Flow the Solder Joints

  • Using a soldering iron (we use a 40 watt Weller with a small chisel tip) and a secondary tool apply pressure to a resistor pushing it into the board with the secondary tool
  • Heat the solder joints with the iron and flux until the joints has been completely melted and reformed
  • Repeat for the second joint on the same resistor
  • Repeat for all seven remaining resistors

Re-install and Enjoy!
