hey everyone back to the drawing board again today after not having any heat blowing this cold morning. just to give a background the heat did the same thing a couple of months ago it would intermittently shut off and on every couple days it being off for only 5 min max then one day just shuts off completely blower and resistor were brand new at the time so I changed the control unit on the dash and it fixed the issue maybe 2 months later today same symptoms were happening then bam no heat on my 30 min drive due to the blower not blowing. also id say once every 20 to 30 cold starts ill get to my car and see none of the gauges are working and the T/C light is on. shutting off the car for 10 to 15 sec fixes the issue but this does not work for the heat sadly. also gunned it getting onto a main road today and got a charging system failure warning car runs fine and didn't do anything weird when the light flashed on but im sure its a symptom.

alternator is a refurbished unit only a year or two old and battery is only a year old im thinking I have terrible grounds and was thinking of trying to do the big 3 upgrade but wasn't sure if its a good Idea and I don't know exactly what to do with it.

let me know what you guys think id hate to have to get rid of this thing after how perfect its running and how fun it is for something silly like this but I don't want to be fixing my heat every 2 months either haha
