Not sure when it happened, but in he last couple months, when I push the button for the VENT or any AC function, its as if I push the OFF button on the climate controller in my 93 w250. Vent doors move, but the blower stops. Not a huge issue recently, because the HEAT and DEFROST still work just fine, but summer is just around the corner. Is there something simple I can check? Or is it likely time for a new controller piece? I have not checked anything yet, but wanted to get ideas first.
On a related note, my blower doesnt seem as strong as it was a few years ago. Getting 14 volts to the plug in at the blower motor. Could 20 years and 400k be the end of its life expectancy? Where can I get a new one? I know, parts store, but I have had crappy luck with any parts store electrical stuff the last few years..... I want to replace it once and be done.
