Is there a fuse for the heater

Here are some steps you can try to troubleshoot the issue:

Check the power source: Ensure that the heater is plugged in and the outlet is functioning correctly. You can test the outlet by plugging in another device.

Reset the heater: Unplug the heater from the power source and wait for 10 minutes before plugging it back in. This will reset the heater's internal thermostat.

Check the fuse: If the heater still doesn't turn on, check if the fuse has blown. You can do this by opening the fuse box and looking for any blown fuses.

Contact customer support: If none of these steps work, it's best to contact DeLonghi customer support for further assistance.

blower fan fuse should be in main fuse block and usually labeled heater. If not labeled, use test lamp with heater fan turned to on to test both sides of each fuse. Find one hot on one side only, pull and replace.

Check for the heater relay. It's an industrial type "fuse".

The turn signal fuse I could see if there was a short in the wiring in the column, but the heater fuse surprises me.
It could be in the column, or in the harness going to the transmission.

check all 20 amp and check the 10 amp fuse to heater and air conditioner control, problem could be in the heater and air conditioner control switch,let dealership check it out.

there are a few things that will cause this problem.
1. it could be the heater fan fuse
2. could be the heater fan motor itself
3, a bad switch or relay

check the fuse and then check for voltage at the heater motor itself, if you have voltage at the heater motor,, give the heater motor box a love tap with your hand and see if it starts to turn, if it does not turn or even if it does ( after tapping it ) - it is time to replace the heater motor.

open hood,look in main fuse box for blown fuses,or bad relays to heater fans. the a/c fan should come on only when you turn a/c on at the dash panel only. it has nothing to do with the heat. if the heater blower fans don't come on, then look in the main box[fuse] for a blown fuse also. otherwise the problem is in the heater control module.[where you turn on a/c and the heat] that panel has a different fuse location.under the dash drivers side or on panel on drivers door at the door jam[where the door shuts towards the front of car,under mirror,but inside] look for fuse panel there also for blown fuse. hope this helps,but if not,recommend you seek a pro.such as cadillac

There is obviosly a short some place. A temporary fix until the short can be traced is to remove the heater fuse. Locate the fuse panel. It is usually under the dash on the driver side but has been known to be on the right hand side under the dash or maybe even in the glove compartment. Once you found it then read the cover and locate the heater fuse. Remove t and save the fuse to replace at a later date.If the heater fuse operates more thenone feature such as windshield wipers or radio and so onthen you will need to leave the fuse in if you want the other features. Another option is to remove the negative battery cable when the vehicle is not in use to prevent the battery from being drained. I hope this helps, The Raz

fuse blows. unplug heater blower motor turn ignition on, turn heater on, does fuse blow? if not need to replace heater blower motor

It is possible but not very likely. check your floor console fuse block and look at fuse 25(blower) or fuse 26(temp motors)
