Hi i just joined your club... i am having problems with the heating control panel on my 1999 european blazer lt. it is not showing any signs of life at all now, after a changed battery it did work now 2 month later and having not been used it is totaly dead. i read and read and read all sorts but not got anywhere . i am not technicaly astute so most of the jargon used goes over my head . i tried to work put how to reset the ecc , but again failure . can you explain in simple terms this reset procedure .. i have no idea what the DLC connector is either, as i said i am not so good at mechanics. thanks if you can offer me any help .
