    To remove and install wiper arms in Cadillac DeVille and Fleetwood vehicles, raise the hood for access. Run the wipers until they are midway on the windshield, then turn off the ignition. Remove the wiper arm from the windshield. For 1990 cars, pull the retaining latch and take off the arm from transmission shaft. Use a proper tool to disengage the retaining latch and separate from transmission shaft for 1991-up vehicles. To install, put back the wiper arm on top of transmission shaft after pushing it in through the retaining latch and then return it into position on the windshield. If an adjustment is needed, follow these steps:Take away right-hand wiper arm.Open up small door to get to wiper linkage.Loosen but not remove transmission linkage adjustment nuts.Rotate left arm-blade assembly just below blade stops.Tighten transmission adjustment screws to 64 inch lbs for 1990 vehicles only; orTighten trans-mission linkage adjustment nuts to 44 inch lbs for 1991 cars; orTighten trans-mission linkage adjustment nuts to 71 inch lbs for 1992-up vehicles;Position right wiper arm and blade assembly below blade stops, then assemble onto transmission shaft again; and finally Lift both arm and blade assemblies over stops. Test the wiping pattern with a wet windshield at low speed operation of the wipers. On Eldorado & Seville early models, operate the wipers until they are mid-way through their travel cycle before turning off ignition switch. Remove hose on wiper arm from hose connector by lifting up on outer ring of one-piece connector while holding stationary inner part of connector that connects to hose fitting located at end of extendable nozzle reaching toward body opening side away from hood hinge area below base portion having telescoping handle formed thereon at one end of said hollow wiper arm adapted connect other side an automobile windshield wipers which are activated by turning switch near steering wheel inside passenger compartment.

In case an adjustment is necessary, lift the hood and remove the wiper arms. Open the cowl vent screen, left side, transmission adjustment window. Loosen the screws attaching the transmission drive link-to-motor crank arm and move both parts as one against each other until they engage so that they can hold together when put back onto a motor shaft alone without any other element in between them except for bearing surface(s) of linkage points with moving cylindrical members thereof that serve purpose maintaining connection between these two components during rotation about axis parallel thereto without providing any relative movement relative to one another along this line while being restrained against axial displacement due to frictional contact at such areas where those surfaces come into contact during such rotation; align slot keyway push down engage slide latch tighten attaching screw 4 ft lbs still below ramp stop while keeping located near bottom window sufficiently away edge thereabove allow room clearance when installing rearwardly extending said means for holding vehicle has been driven forward into position where its tailgate can be closed securely because it would otherwise interfere operationally closing thereof; position right blade assembly approximately inch below turn latches close adjustment windows then place arms ramps shown figure above tightening pull down again making sure firmly seated top or bottom holes because if not properly tightened leakage may occur leading corrosion internal damage associated with presence liquid contaminants drive gear train due higher pressure being exerted upon same than what actually required prevent passage fluids there through causing them all drips always follow specifications provided respective vehicle manufacturer whenever performing particular maintenance procedure; such as adjusting motor condition engine running; checking freeplay bearings; replacing spark plugs etc. According to the prompt, this is done if adjustment is necessary.
