So i removed the battery once and when i hooked it back up, the temperature gauge flashes shortly after start up, and I get cold air and AC fine, but no heat. I will note that regardless the set temp, upon start up i get warm air then goes straight to cold. so i know the modulator gate works because sometimes it will actually give heat, but when i shut off the car and back up it doesnt stay hot. Also the fan speed wouldnt work sometimes then I play with the buttons and usually hitting AUTO the fan speed works. also recirc hasnt worked in a while. is my climate control broke? can i fix it some how? i even had it go through 50 cycles and that
