Legend models begin with disconnecting the negative cable from the battery. The front console and the radio are then removed. The four mounting screws are removed next, followed by detaching the heater control cable. The A/C Switch is then pulled out of the dash far enough to unplug the electrical connector, and then pulled the rest of the way out of the dash. Installation is the reverse of removal. The engine is run and checked for proper functioning of the heater and air conditioning. For Integra models, the process starts with disconnecting the negative cable from the battery. The glove compartment is then removed. The hole covers and the mounting screws are removed next. The control is pulled out slightly. The air mix cable at the clamp is marked to ensure installation in the same position, and then disconnected. The wiring from the A/C Switch is detached and the assembly is lifted from the dash. To install the unit, the above procedure is reversed. To adjust the cable, the mark made is aligned. The clip is fastened and checked for stiffness or binding through the full range of operation. The engine is run and checked for proper functioning of the heater and air conditioning, if equipped.
