Which fuse is for the heat/ac??

Nothing but cold air coming thru the vents. Got the climate control switch turned to red for heat. When the temp gauge gets to the middle is when I try the heat it also pauses and runs cold air thru the vents. No Smell coming thru the vents either.

Low coolant level will cause a no heat condition - that’s something the DIYer can check .. Otherwise - recommend seeking *hands-on* help from qualified personnel.
