a/c blower install

Ok guys ordered the a/c blower motor as suggested. Now, how the hell do I get this thing in there? Does anyone have instructions on what I need to remove to get near the blower motor? I removed the front plastic cover that goes around the gauges but cant seem to reach the other three to four screws that hold on the a/c vent cover. Any help would be appreciated as I am working off my phone and I'm in the parking lot of my work trying to fix this thing in 100 degree weather.

a/c blower

You will need to remove the unit from under the dash to get at the screws that hold the blower in place< not an easy task in a parking lot; Good luck

A/c blower

from Jeep44 post:
Did mine a few months back. I got a 90 with factory AC. First, remove the battery, battery tray and two coolant lines that hook into the heater core. Now remove the four nuts that hold the heater box in place. These are located on the engine compartment side of the firewall. Three are on the passenger side and the fourth is just to the drivers side of the valve cover. Now that you have that removed, move to the inside. Remove the four screws that hold the AC unit into the dash. There might be more, hard to remember. The 4 are located at the bottom of the dash. Now you can lower and move your AC unit around. Careful not to break any lines, just work it slow. The heater box will slide out. It is tight, so expect to make some turns with it. Now switch the blowers. Enlarge the hole in the firewall with a dremel or jig saw as I did. Make it big enough so you will not have a bad fit, you only want to remove it once. Now reinstall everything. Enjoy the heat. I also installed a 190 thermostat for winter. My YJ gets so hot that I rode around with a t-shirt and the fan on low on a 30 degree day.

Why would I need to make bigger holes in the firewall. Is the new blower motor bigger than the original?
