Re: My heater is not working ( not coming on, not blowing...
Are there any fuses under the hood in a box located on the firewall. You can buy a cheap tester for less than $5 at walmart. it has a probe, light and an alligator clip for ground, find a metal point close to the fuse box, unpainted preferred and use probe to touch little metal points on fuses, both sides, lite should light with power on with engine running and most should light with key in pre ignition position, if tester does not lite there is the fuse.

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.
Hello! Identify which fuse is blowing...also, does it blow as soon as it is installed or does it blow when you turn the key? Lastly your not referring to a fusible link but a maxi-fuse...ie...40; Correct?
There are fuses for hi and low blower fan inside the interior fuse panels I know the high one is on the passenger side and believe the low is on the drivers side tho they may both be on the passenger side read the cover after you pull them off easy to find once you read the label if those are both good then its probably the blower resistor, fuse check first.
