Yeah its not really that bad once you pull the windshield washer/radiator resivoir and plastic inner fender out so you can have room to get it out. BTW there is one nut you have to remove under the dash on the passengers side floor

is that nut hard to get to on the inside? will any of the components that it houses come with that? in other words, is anything mounted to the housing? also do u think that would cause me to lose refrig?

The evaporator is mounted on the inside and the accumulator(the round black canister) on the outside. If you are losing freon gas and your housing is cracked its a good possibility the evap is leaking. A sign of a leaking evaporator is an weird oil smell coming from the a/c and a general sign of a freon leak is a oily spot where there are any line conections or the front or back of the compressor. If you are not losing gas just blowing warm air the cracked housing is probably the problem. There is alot of heat in the engine compartment when driving and outside temps are hot. The nut on the inside is easy to get. its on the bottom of the black heater housing near the fuel reset and where the vac lines come thru. If you are going to the junk yard to get a new housing they should be the same from 96-10 and they would probably include the evaporator. They will probably want to sell you the evaporator and give you the housing.

On a brake master cylinder with cruise there is a extra brake sensor. There should be a plug hanging somewhere in the area with nothing pluged into it. You just have to make a jumper wire for the plug. Thats what I did on my 2000 and it works normal. If you can't find it let me know and I will go look at one for the wire colors.

On my 99 it was attached to the plastic inner fender with one of those push in connector type deals, right below the master...
Anyway the wires are black/yellow and green/violet.

Are you using a used clockspring? The reason I ask is it needs to be centered when installed with the wheels straight. I changed the whole column when I added cruise to my 2000 so I could get the tilt.

yeah that lines up straight but make sure the wheels are straight when you remove it. It could be lined up but not centered if the wheels are not straight.
