This is a very involved process that I could not begin to express here how its done. Check with your local library for a Chilton's repair manual or comparable service manual so you can get very guided details including pictures.
This is no fun I am doing this as I am writting today.
First you have to remove the dash. There are various 10mm bolts and Philips head screws.
There are wiring clips on the radio, the headlight switch (there is a button in the rear of the headlight switch to remove the switch rod)and on the gauge panel for easy removal.
Then I would suggest you remove the internal engine cover for easier access. That takes a 1/2in. socket. There are 2 hoses to the left side of the engine bay. You can see those clearly if you remove the air intake rubber duct. The upper hose has the heater control valve on it and the lower one is a return line. These will need a flat head screwdriver or a 10 mm socket to remove the hose clamps.
I am right now trying to remove all the corresponding duct work to free up the heatercore box.
I removed all the duct work, then I found that there are a few bolts that go through the firewall to the a/c box on the engine compartment side. remove the 3 nuts and there is one bolt on the inside right hand side. There is a bracket that holds the dashboard bottom remove that also with 1/2in or 13mm.
Finally the heater box can be removed. you need a 1/4 in socket to split the heater box. there are like 15 little bolts for this. once the box is split you will finally see if the heater core is bad.
I started at this point to split all the duct work in half and clean it with bleach. Once that was done I replaced everything.
work slow if you rush disasters with wiring and vaccum hoses can occur.

Drain the water from your 1990 Chevy Corsica cooling system. Remove the heater core water supply hoses. Remove the heater core retaining bolts. Reverse the process to install the new heater core.
how to replace a 1990 Chevy Beretta battery
Take out the whole dash and then the heater core should be behind the glove box on the passenger side.
Where is the Water Pump located and how do you replace it on a 1990 Chevy Corsica?
It does not have one.
No it will not
comes out inside . remove glovebox and go in that way . about one hour .
You may want to check your model year. There is no such thing as a 1990 Durango.
You pretty much have to remove the entire heater box under the dash on the passenger side
No. The problem is most likely your heater core. Ask a mechanic.
Yes it did. I own (still) a 1990 Astro camper-conversion van with crank up windows.
check/replace spark plugs
I've been trying to figure out the same thing.
The 1990 Chevy Caprice number 13 fuse is associated with the heater blower motors. The number 13 fuse will be in the second column, third from the top.
the ignition keys are dealer only items.
disconnect the hose and remove 2 bolts.

Wikipedia says 210 hp and 300 lb-ft.
If its just the cord, then follow the old cord to the back side of the engine ( really the side of the engine closest to the firewall ) and replace it. When the engine is cold, plug it in and you will hear the block heater heating up. If you don't hear anything, then replace the heater also. That requires a little more knowledge.
Simply take the old ones loose with the clamps and put new ones on. You may want to replace the clamps .
One of these things is the cause. Thermostat stuck open, replace it. Heater core stopped up, backflush the hearter core, and service the cooling system. Heater temperature control valve defective, replace it.
