Question about 2001 Toyota Opa 2.0
The heater is not working in my car. The fan and air con work fine. There is just no heat coming from the heater. Which fuse do I check to see if that is the problem?

There is a valve on one of the heater hoses that allows heated water to flow through the heater core when you select heat. With heat selected and car warmed up check to see if both of the hoses feel warm. If not then water is not flowing through heater core and valve may need replaced or heater core is stopped up.

Usually this will be a 15 amp fuse, and usually blue. This should narrow it down. Pull one out, see if its blown. If you can't tell, put a new one in, and move the old one down to the next blue one. Eventually, you will figure it out. Then I would get an owners manual in english, or buy a dash cover at junkyard, so you will have it for future information. A dealer should be able to print, and give to you a fusebox diagram, then you can glue it to the inside of the fuse box cover. There are also some master fuses under the hood, 30 amp and above.

Quick tip that might help. Under the glove box is the blower fan, check the plugs that run to it make sure they have a good connection. then give the blower fan a little tap, mine was just stuck. could have been from dust or something. Or a plug might have been loose.

This problem is specific to the Gen4 Celica (86-89). Intermittent or no heat heat is caused by cracked
solder joints in the Heater Control Panel. You need to remove the panel
and re-solder the solder joints. When electrical continuity is broken,
the panel defaults to the cold setting. If you go over a bump and it
touches again, you may get hot. Hence, intermittent or no heat. We have
the complete DIY fix posted at www.st162.net and it's free. Pic below shows the heater control points to re-solder.
