Been maybe 3 weeks without ac I couldn’t figure it nor did I have the time. Id it common for the ac decks to go bad?

anything that runs the big current can melt or go bad.    this includes the headlight switch which is why the relay kits are popular.

Been thinking about getting one of those here soon at the same time I ain’t seen any need to at the moment I will soon though

Doesn’t take much. A little corrosion or slightly loose connection, coupled with heavy current from an aging blower motor, and things are gonna get HOT. 
But there’s your classic example of a multimeter misleading you. Just a hair of connection to show you 12V at the motor, but put a little current through and it can’t handle it anymore.

have you inspected your headlight switch plug?  how bright are your lights?

My headlights are pretty bright but they are leds though. And as far as the plug it looked fairly nice the last time i checked it but no doubt will do the upgrade just to be sure the same plug we are talking about is the one the headlight harness plugs into right

[Pete M]

I mean the harness plug that attaches right to the pull-out headlight switch in the dash.  the one that likes to catch fire now and again.

To me, the headlight upgrade harness is a must have. 

 

Wait til you need it and it will be at night..............
