Volvo Climate Control Panel Removal
How-to remove your volvo climate control panel.
The Electronic Climate Control (ECC) module (A/C-heater control panel) contains a function selector dial, driver’s and passenger’s temperature dials, a REC (recirculated air) switch, A/C OFF switch, and a fan speed (blower motor) control lever. The heater (blower motor) fan is controlled by ECC output (power) stage. Air conditioning system will only operate above 32 F (0 C). Blower switch must not be in zero position to allow compressor to engage.
Other system components include an A/C relay, A/C compressor, low-pressure switch (pressostat), A/C safety and high-pressure switch, engine coolant temperature sensor, outside temperature sensor,
interior temperature sensors, and duct temperature sensors.

I own a sharp-looking 1994 850, red with tan leather plus sunroof. When I turn on the headlights, the heating and ventilation control panel lights do not light up. How do I gain access to the lights/and or how do I remove and replace the control panel? (The radio is easy to remove, but I can’t figure out what holds that heating and ventilation panel in). 😕 Thank you!

For the Electronic climate control panel:
With the radio out reach in the aperture and depress the locking button on the underside of the unit. Push out one rear corner of the unit to free it from its location and then remove it from the facia. Disconnect the three wiring connectors.

I have had the distinct displeasure of removing my control panel manual unit. Completely removing it is a full on b I itch. I had to repair the drivers side temperature mechanism so I had to completely remove the unit unfortunately I didn’t pay much attention to the lamps but I’m fairly certain that you can get to them without completely removing it.
To remove the unit you first need to remove both temperature knobs, the air mode knob, and the fan speed knob. They pull off but they don’t pull off easily. I used a pair of pliers with a rag wrapped around the jaws so as to not mar the knobs.
Once the knobs are removed 2 screws will be revealed behind the temperature control knobs. Remove those screws to access the control mechanism. From there you might be able to get to the bulbs directly but I actually think you will need to got further. I’m working on memory but I think there are a couple more screws to release the assembly and I recall that you will need to remove the Fan switch and the AC/Rec switch assembly.
I’m thinking that the bulbs are the same as the goofy bayonet base bulbs that are in the instrument cluster, a dealer item.
