Disassembling

You're going to have to do a lot of disassembling. Here we will not into details about how to disassemble all that stuff, you really should have a Workshop Manual before trying a project like this one. It is really recommended to make sure you have all required parts and tools before disassembling.

First remove your front console where the shifter is, then remove the center panel where the stereo and cigarette lighter is. Now you can remove the heater control panel and center air vent. It should now look like on the picture at the left.

Now remove the glove box, the dashboard lower cover, the knee bolster, the tweeter covers, the visor trim panel and the display visor. Remove the 2 screws under the steering wheel, and disconnect the air bag and connect the red connector. Remove the steering column covers and the air duck under the steering column. You can now remove the 2 nuts and 2 bolts that hold the steering and steering column in place and lower the steering on the floor. If you have a passenger side airbag disconnect it and put the red connector on it. Disconnect the 3 connectors on the driver side near the fuse box and the 2 connectors on the passenger side. You can now remove the 6 bolts and remove the dash. Be careful when you get it out of the car so you don't hit anything.

With the dash out of the way, removing the evaporator is quite easy. First make sure you get your A/C system emptied by a professional. Releasing Freon in the atmosphere is illegal and you might be able to get a few bucks if you have a 92 with R-12 in it. Now there's 1 nut and 1 bolt you need to remove under the hood, then there's 5 bolts and 2 nuts inside the car. Disconnect the A/C thermostat and you can pull the evaporator out. Be careful when you pull the evaporator out not to break the pipes, there's one that you'll have to lift up a bit to be able to pull the evaporator. Just remove the 4 bolts and remove the heater duct (cars without A/C) out of the way.

Here's one of the bolt for the evaporator under the hood.		And that's the second bolt for the evaporator under the hood.		The evaporator is removed.

Disconnect the 3 connectors from the blower unit. Once in from on the blower resistor, the other one on the left side on the recirculation control motor and the 3rd one is under the unit on the blower motor. Now there are 2 bolts and 1 nut to remove and pull out of the way.

This one is more tricky, first you'll need to drain the coolant. Then you'll need to remove the intake tube and a few brackets on the firewall. You should remove the bracket holding the MAP sensor and the one under it. Disconnect the heater valve cable from the heater valve and disconnect the 2 coolant hoses that go through the firewall to the heater core. Those 2 hoses can be really hard to remove, so you can get some new ones and cut the old one off. They're not expensive so it's worth replacing them to save the trouble. Now a bit below where the hoses where connected and a few inches to each side, there are 2 bolts that pass through the firewall with nuts on them. You'll need a 12mm deep socket to remove them. Then you can remove the 2 bolts inside the car on top of the heater unit. The one on the driver side is going to be a bit harder because it's kind of hidden. Now you can pull the heater unit but be careful because there's still coolant inside the heater core and it might spill in your car.
