ROOF PROBLEM HOLDERN ASTRA SOFT TOP CONVERTIBLE. HOW TO TOP UP HYDRAULIC FLUID FOR ROOF

Lots of problems with those roofs. Take it back to the place that fixed it and tell them to fix it properly. Probably air in the hydraulics.

Low on hydraulic lift motor fluid due to a leak in the lift piston or pistons

there is a small master cylinder (similar to where you put brake fluid) you add fluid just as you would your brakes.

If you are refering to a hydraulic clutch, there is a master cylinder similar to where you put brake fluid. you top it off the same as you would your brakes.

If you can close it manually with no obvious problems then opening it manually if there is no effort required should be ok. I would be checking the limiting position switch adjustment as that is what would be preventing from it closing all the way up

You have to put hydraulic fluid (power steering fluid will work too) in the convertible top motor. The motor is in the trunk, on the left hand side, under a panel. Pull the panel off and that is the electric motor for the top. You'll see a reservoir where you put in the fluid. Put in the fluid and you'll be good to go.

Hi David:

First, check the fuses for the hydraulic motor; if they're blown, replace and monitor (why did they blow? Perhaps an overload, or ...) These fuses are located in the engine bay on top of the fender by the front right wheel housing.

Next check the voltage supply to the top switch, possibly a loose connection or broken wire.

Also check relays C (raising top) and D (lowering top) under the rear seat.

Lastly check for voltage at the pump, also under the rear seat, when the switch is actuated, and that the voltage polarity reverses when the switch is actuated the other way (up or down).

After that, it's a hydraulic/mechanical problem. Check the fluid level in the pump reservoir (use SAAB fluid to top up if low) Fluid level should be at the upper marker with top down, and at the lower marker with top up.

Check behind the rear seat side panels that the piston shaft is still properly attached to the roof mechanism bracket at one end, and the piston itself is still firmly attached to the body. Look for any leakage from the system.

If all tests out OK and looks good under the rear seat and behind the side panels, then there is the possibility that the piston seals have failed and the fluid is just circulating around without activating the piston. Pistons are available (http://www.convertibletopguys.com/cgi-local/displaycat.cgi?cat=584 - scroll down) but the entire system should be removed to avoid getting hydraulic fluid on the interior.

However, that fact that you can operate the hood using the bypass valve (manually) would indicate that the hydraulics are likely OK, and that it's probably an electrical or mechanical problem.

Good luck!
