Check all of your lines leading to the pump and see if there is any evidence of hydraulic fluid leaking in the rear quarter panel on both sides of the car. Hydraulic gear oil from your local auto parts store will do fine. Check the cap on the pump and make sure it is tightened properly after topping off fluid. Pump should make a slight whining noise if it is working properly.

Do you check the hydraulic fluid level, on my 1997 Sl 500, with the top up or down?


Top needs to be up when top is down the Pistons extend with fluid showing it is low and if you fill at that time when you close it the Pistons will go back in and fluid will run out and possible cause of a leak

I HAVE A 1995 M B 500 SL THE SWITCH INDICATOR FOR THE TOP & ROLL BAR STAY IN A BLINKING POSITION. THE TOP, POWER WINDOWS AND ROLL BAR WILL NOT FUNCTION AT ALL... THANK YOU


The control module has set a fault and it will have to be reset. They are sensitive to voltage & must have 12 volts to operate properly.
The windows and top will need to be resync. I cannot find any information regarding the diagnostic procedure for the roof .. it states there is a procedure to diagnose the fault with the number of flashes the switch makes .. a dealer may be your best option on this fault .. I hope this helps some.

1996 audi cabriolet 2.8 V6 convertible top motor needs fluid how do i add the fluid to the convertible top motor?! and what type of fluid does it need?


Almost all power convertible tops are electric over hydraulic. The ecectric motor runs a hydraulic pump. The pump pushes fluid to the cylinders that work the top. Most are located behind the rear seat backrest. Either remove the rear backrest or access the motor/pump from the trunl. It will be shaped like a cylinder. At one is the electric motor, at the other end is the hydraulic reservoir. At the end of the reservoir is a rubber plug. With the top down, remove the plug and fill it with tran fluid till it over flows. replace the plug and cycle the top up and down as far as it will go. Repeat the process till it will take no more fluid. A turkey baster with a piece of vacuum line makes a good filler tool. With that said, you must find the leak. You may have a leaking pump, hydraulic line or cylinder. RNever replace one line. Do them all. Always replace cylinders in pairs.

Good luck, Karl at aoksales.com

I m having problems with the convertible top . you could hear the motor runing on it but the top does not go up or down please help


the hydraulic fluid may be low. the pump is located in the right side of luggage compartment. it has a plastic fluid reservoir which often has hair line cracks near the mounting screws. fluid seeps through cracks. reservoir needs to be replaced.

1995 Jaguar convertable XJS quarter light windows wont go up


The rear windows are controlled by a timer in the top's ECU. If
the rear windows stop fully closing before your top is closed, the
problem MAY be with top's hydraulic system.

Check your top's hydraulic reserve tank for low fluid level. Lack
of fluid will greatly delay the top's closing sequence, leaving
those rear windows partially open.
Your top's hydraulic pump system is located beneath the right side
of the cubby/storage box behind the front seats. Raise the cover
and you'll see a removable trim panel on the right side. The pump
is behind that access panel.

You can use power steering fluid to top off the tank, but don't
fill it above level indicator line. You may have to add more fluid
after you cycle the top up and down to get the air bubbles out of
the lines.
It could also be a relay. On a 95 the relays that are in the trunk above the battery.
Perhaps, just switching the relays might prove which one is failing..

19886 saab 900 convertible roof not working.


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!

Top won't go all the way up.


I had the same problem. One day I opened the hydraulic resevoir under the spare tire to check the level of the hydraulic fluid and voila' the top started to work fine. It opened and closed perfectly. It has worked fine now since July. The only thing I did was open the resevoir. Perhaps there was some kind of air block!
