Was it recently flushed or changed? On my Duetto there is a bleed valve, passenger side near the firewall. Crack it at idle and air should escape and then anti freeze. It should be open during refill and closed when Anti Freeze comes out and finish filling.

After a bit of a layoff, I got a wad of crud that blocked the valve diaphragm (heater inlet). I backflushed, blew out the crudand the heater and it was fine. Another time an old swollen valve diaphragm did it.

Heaters in these cars are really efficient when all is good, warming up quickly and blowing hot (not just warm) air within minutes of starting up. Given your question about fuses or relays, I am surmising you are not aware that it’s hot coolant from the engine, flowing thru the heater tap and the heater core (which looks like a small version of your car radiator) which provides the heat. No electricity is involved.

Do (did) you get hot air, pretty quickly? Have you noticed a slow deterioration in performance, or sudden? The smaller diameter rubber hoses going thru the firewall to/from the heater should get hot if you have flow. Feel them when the engine is warm (heater valve open). This is the simplest test. I saw a picture in a recent thread showing a totally blocked hose.

If things don’t get hot, a flush is definitely worth a go. Easy enough to disconnect the inlet/outlet hoses inside the engine bay, putting a garden hose into one end and pump some water thru, hopefully flushing any crud out. Reverse direction to normal heater flow is probably best, which (I think, logically) will mean put the hose into the longer rubber hose going back to the front of the engine...but little harm trying both directions. You will lose a bit of coolant, but you can minimise this by plugging with a bit of rag. It might be time to flush everywhere and renew coolant anyway.

Provided your heater control lever is actually opening the heater tap (barring the swollen diaphragm problem, you can see/feel this if you get down and dirty under the dash and look), and you have bled all the air out as described, a blockage is indeed key suspect. Good luck!
