Have a TOYOTA rav4. The heater fuse 50 amp was blown. When I replaced it. The new one blew as well. Wondering if there is a relay issue?


Never heard of a relay problem blowing a fuse. Believe either your heater motor has an internal short, or a short in the wiring to it, like bare hot wire touching metal.
That's a large fuse. Are you sure the heater circuit is the only circuit for that fuse? If it is, makes it easier to find the short. Unplug the heater motor and see if new fuse blows with key on, and heater motor switch on. If fuse don't blow out, probably your heater motor. If fuse blows , could be your resistor pack for the heater or a wire touching metal, it should cause a large spark and a "pop" when it blows fuse.

My heater doesn't work on my 06 buick rainier


A few things to check would be your fuse, refer to your manual to see which fuse controls the heater and if your fuse is good your heater coils for your heater might be burnt out. Or maybe just a loose connection to the heater coil.

Heater system


There are three fuses involved, all of which are in the fuse box in the dash.
15amp radio hvac powers the control module on the dash.
10amp hvac also powers the module.
30amp high blower fuse powers the blower motor only.
Check your owners manual for details.

Fuse panel for mazda rx-7 which is heater fuse 1983


If it is the fuse for the blower try this to see if it helps. If it is the blower fuse looks like a 20 AMP fuse on the right hand side 4th one down. may be numbered number 11

I hope that helps.

I am getting in heat... We know it now the heating core... Do you have any idea what it is


If it isn't the heater coil, then the only things left are the heater fan fuse or the heater fan motor itself. Check your fuses. If you don't have a fuse diagram, start with highest amp fuses first. The heater motor uses a lot of juice and will probably be on at least a 10 amp fuse. If all the fuses are good then you probably need a new heater fan motor. They usually mount to the fire wall from the engine compartment and are pretty easy to change. Not at all like the heater coil.

Where is the fuse for the heater on a 1991 toyota pickup. my heater was working when i got out, and the next time i got in, the heater fan would not work. no noise , no nothing


Check the fuse box under the dash, which you may have already done, also check under the hood there is a secondary fuse box and it will list the heater and fuse or it may have a relay for the heater, you my have a bad relay for heater.
