	The matrix/blower assembly is held in place by 4 screws. Remove the metal [http://www.eliseparts.com/products/show/84/166/flexible-heater-ducting/ flexible heater ducting] and the hoses into and out of the matrix itself. One of the screws is just inside the outlet from the blower where the hose attached. Two are into the bulkhead below the radiator behind the cylindrical green ceramic terminal block. And the fourth is closer to the battery again into the bulkhead below the radiator. It's easiest if you remove the green ceramic terminal block - it's simply held on by the metal at each end which can be squeezed together and pulled out of the center of the green cylinder. Early Elise models had 3 cylindrical terminal blocks mounted on the blower. Later models had just one.		The matrix/blower assembly is held in place by 4 screws.

	The wire which controls the hot/cold flap sits on top of the assembly. ~~This should~~ be removed. ~~The~~ sprung metal clip ~~holding~~ the ~~cable in placed can be levered off~~ and the S-shaped end of the wire can be removed from the control armature.		The wire which controls the hot/cold flap sits on top of the assembly. It cannot be removed while the cable is held by the spring clip and the flap arm is attached. Either lever off the surprisingly strong sprung metal clip or remove the attachment on top of the flap lever, and then the S-shaped end of the wire can be removed from the control armature. The flap lever is held on with a #10 UNF grub screw (3/32" allen key) and if this is not rusted solid then the arm itself will be corroded on to the flap.

	Once the matrix/blower assembly is free, it may still not be possible to get the unit out of the vehicle. The [http://www.eliseparts.com/products/show/61/182/heater-blower-fan/ blower] is connected to the matrix by a metal strip and nut both on the top and the bottom of the assembly. As the matrix/blower assembly is now free and has a certain degree of rotation within the car, the matrix can be separated from the blower by undoing the nut and rotating the metal strip about 30 degrees. The metal strip on the bottom of the assembly is identical. The nuts are prone to rounding or shearing, in which case you will need to drill-out the rivet instead.

			Take care to orientate the motor so the small hole in its case is facing the ground when it is fitted. Failure to do this will result in your motor filling with water when it rains (don't ask how I know).

	Re-assemble matrix/blower unit and then screw it back into the chassis - this may need two pairs of hands and a lot of patience due to the location of the screws.
