To take out a blower motor for 1999 models (excluding Seville), first disengage the cable from the negative pole of the battery. Then, if available, remove strut tower cross brace and bracket from relay center. Relocation relay center and MAP sensor to one side and remove ignition coil assembly in addition to solenoid purge valve as well as any other accessories if required. Cut rubber insulator and take off metal patch plate from engine compartment, also remove inertia plate from blower motor case. Disconnect wiring connector and cooling hose from blower motor, unfasten mounting screws pulling blower assembly out of housing. Tilt the blower motor under if there is not enough room unscrew nuts on the fan so that you separate it from its' respective blades and then pull out your fan separately together with a motor. For Seville of 1999 and 2000-2005 models, extract trim panel, carpet backward then pull glove box through it right space. Take away dash integration module with its mounting bracket; disconnect wire connection of a blower motor and then get rid of securing screws before sliding out this assembly through its cavity/compartment. Exclude lower insulator panel at front passenger's side as you undo electrical connector meant for air conditioning system's evaporator/fan thus releasing it completely using two compatible bolts only. While removing auxiliary blower motors excluding those in Seville of 1999, you have to dismantle central console rear cover after which electrical connections will be disconnected plus fasteners withdrawn allowing fan to be separated from associated engines by means of some holding clips alone; thereby enabling these blowers upon which they were installed with respective bearings for instance or even casings themselves may easily be replaced without necessarily replacing whole systems entirely unlike such fans themselves treated on most vehicles usually as disposable items altogether except retrofitting purposes obviously because they do not employ energy-saving devices like brushless DC motors generally found every other appliances for instance. For Seville of 1999/2000-2005, get rid of center console; electric connector must be unplugged, air ducts disconnected, bracket removed and finally blower lowered until its' separate from rear air duct. However, you will have to remove the whole instrument panel by first taking out carpeting followed by conduits then let the auxiliary blower motor support come out completely. Remove central console but disconnect power connections along with unfastening screws that lead to detachment of spare fan case having a motor inside. Everything is in reverse order during installation process.
