2000 Chevrolet Camaro Convertible Tops Power

Convertible top is controlled via a center console-mounted convertible top switch which provides power to hydraulic pump assembly. System is protected by power window circuit breaker (30-amp). Pump assembly consists of 2 hydraulic cylinders, by-pass valve and reversible permanent magnet pump motor. Pump assembly has 2 hydraulic hoses for each cylinder that evenly control up and down movement of convertible top. See Fig. 1. Pump motor is protected against internal overload condition by an electronic circuit breaker.
If vehicle battery is low on charge or disconnected, convertible top can be raised or lowered by by-passing hydraulic pump. In rear compartment, locate access hole for pump valve in side trim. Rotate pump valve clockwise 1/4 turn until it stops. Unlock front latches. Manually lower folding top by lifting No. 1 bow near "A" pillar and lowering top as required. To raise, lift at center of No. 1 bow, lock front latches. Return pump by-pass valve to original position.
ON-VEHICLE SERVICE HYDRAULIC SYSTEM BLEEDING
NOTE: DO NOT allow hydraulic oil level to drop below lower indicator line on reservoir or pump damage may result. See Fig. 1. To avoid damage during bleeding procedure, ensure cylinder rod does not touch body components or convertible top assembly when extending.
1) Remove cylinder assemblies from outer arm and main pivot bracket assemblies. Position cylinder assemblies so cylinder rods do not touch body components or convertible top assembly when fully extended.
2) Remove left rear compartment side trim assembly. Remove reservoir filler plug. Remove one Pink hose from pump/motor assembly and place at reservoir filler plug opening. Use a rubber plug and seal open pump fitting to prevent air from entering system. Push and hold convertible top switch in UP position. After cylinders are fully extended, continue to depress switch until hose being bled is free of air bubbles. To install, reverse removal procedure. Tighten hose fitting to 62 INCH lbs. (7 N.m).
DOWNSTOP ADJUSTMENT
1) Disconnect negative battery cable. Open trunk and locate access hole for by-pass valve assembly at left rear quarter inner trim panel. Turn pump by-pass valve assembly to OPEN (fully clockwise) position. See Fig. 1. Lower convertible top assembly. Lay straightedge across rearmost edge of side rail garnish moldings with straightedge extending to left and right edges of vehicle.
2) Reposition plastic splash shield to allow access to downstop bolts/screws. See Fig. 2. Loosen downstop bolt. Adjust octagonal downstop cams so convertible top assembly is level from left to right along straightedge, and allows sufficient clearance for boot cover installation. Tighten bolts/screws to 13 ft. lbs. (18 N.m). 3) Remove straightedge. Raise convertible top assembly. If upstop adjustment is needed, go to UPSTOP ADJUSTMENT. If all adjustment is complete, turn pump by-pass valve assembly to CLOSED (fully counterclockwise) position. Reconnect negative battery cable. Check top operation.
