A dealer would be the best person to give air conditioners for repair, but a capable home mechanic could replace visually defective components after professionally evacuating the system. For access to A/C Switch, remove consolette screws, disconnect trim cover, release fixing screws and detach A/C Switch while disconnecting wiring, vacuum pipes and temperature lever control cable. First return the cable as instructed. By removing the A/C Switch one can get the Blower Control Switches. Blower motor is built into evaporator housing and access is through glovebox removal secured by four fixing screws. Glove box needs to be removed in order to access vacuum motors for various functions. Evaporator removal involves disconnection of battery, draining of cooling system and disassembly of numerous units. Similarly, combination valve and A/C Accumulator have particular steps of removing them that involve; disconnecting refrigerant lines and capping openings. Condenser removal entails activities like pulling out screws, splitting between refrigerant lines and detaching it from its frame structure. Right under the front fender on passenger side is where the A/C Accumulator is located hence demands doing such things as raising vehicle up off ground level then taking down roadwheel or wheel if you like calling it by that name. In refitting processes always ensure there are new O-ring seals on top of adding refrigerant oil into some parts with due diligence being discharged before any marked parts are removed or tested again before recharging at dealer's place following completion of dismantle erect operations.
