I can't seem to get the right words in the Search box to get help on my issue which is on the '94 wagon with 279,700 miles on it. The CC unit only blows low speed if it blows at all. Any suggestions or buzz words to narrow it down? It has all original CC and PBC parts including evaporator and heater core.
