In 10 degree weather in the midwest, started the 1997 Park Avenue ultra to warm up. Put the rear defrost on, on my way to work about 20 minutes after he initial start of the vehicle, I began to smell something relating to burning electrical or electrical components. Upon further investigation, I found the module in the drivers side "c" pillar next to the rear window appeared to be melting/burning. I removed the module and found the power connector to the module had completely melted and almost caused an electrical fire. Due to my experience in electronics and vehicle electrical systems I was able to repair the module and replace the burned connectors with another type of connector. I would recommend anyone that owns a gm with this module, check connections and put electric safe dielectric grease on the connections to avoid arcing and possible fire.
