I replaced the HVAC plate a few weeks ago because I had been driving around for years without a back light. The install went smooth and I noticed yesterday that the AC and recirc buttons turn off (blue light goes off) when using fan speeds greater than 1. I don't remember if everything worked properly immediately after installation. I hear the typical AC tell tales that the compressor turns off. When I turn the fan speed back to 1 the lights turn back on and the AC compressor turns back on. Could have I installed a connector incorrectly when swapping the HVAC plate? Or is this a indicator that the switch pack is about to go bad? I can't say I've seen these symptoms mentioned in the switch pack module threads I've read over the years.
