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.
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?

Remove Console Rear Nut Covers.
- Open the console and find the oval shaped nut covers towards the rear
- The rear nut covers simply pop out with a flat tool. I use non marring nylon trim tools.
Remove Active Handling Panel
- Using a flat tool Remove the panel housing the active handling switch switch
- Simply work the tool under the panel and twist
- A wire will still be attached don't pull the panel too roughly
Disengage A/H Switch Connector
- Disengage the active handling switch connector by squeezing the release tab and pulling away from panel
Remove Power Port
- Remove the power port/cigarette lighter
- This will require the removal of the electrical connector by pulling it away from the port
- Early models may have a screw on retainer for the port
- Late Models have a plastic bodied port with locking tabs that must be turned and maneuvered through a corresponding slot in the console
Slide the Center Console Rearward
- Slide the center console as far rearward as possible
- For convertible slid the console under the rear waterfall it will move enough to remove the radio bezel later
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 the Radio Bezel Screw
- Remove the screw under the inside air temperature sensor cover with a T15 tool
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 Screw Behind Ashtray
- Fully removing the ashtray will expose the last screw
- This screw 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.
Remove Bezel Connectors
- Remove the cigarette lighter electrical connector from behind the radio bezel piece
- Also, remove the inside air temperature sensor electrical sensor connector if equipped
Remove Right CCP Screw
- Remove the 7mm screw from the right side of the Climate Control Panel
Remove Left CCP Screw
- Remove the 7mm screw to the left of the Climate Control Panel
Remove CCP from Dash
- Simply pull the CCP rearward to remove from the dash and expose the electrical connector
Disconnect CCP Connector
- Squeeze the blue tab, then pull and wiggle the electrical connector free from the CCP
Remove CCP Case Half Screws
- Remove the 4 3/16" screws from the rear of the CCP hold the case together
Remove Rear Circuit Board Screws
- Carefully open the CCP case taking care not to stress the wiring connecting the front and rear circuit boards
- Take care to not let the front board fall out or the front buttons to become misaligned
- Remove the 4 3/16" screws fastening the rear circuit board to the case at the corners of the rear board
Remove Rear Circuit Board
- Carefully apply pressure to the male terminals of the electrical connection to push the rear board free from the case
Rear Board Removed
- The rear board should now be free of the case and we can now see the resistors we need to re-flow the solder joints for
C5 CCP Power Supply Resistors
- There are 8 power supply resistors positioned around the board
- There are 2 different rear board designs
- There are always 8 resistors
- They are rectangular, black, and stenciled "241"
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
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!
- Reverse the dis-assembly and removal instructions and enjoy your fully functional full brightness climate control panel
