hydraulic fluid leaking when soft top is raised or lowered.
My soft top simply do not open anymore. I hear all kind of motor trying to work but something still hold all brackets. I don't know if is a switch, vacuum pump or electric issue. With a SRS scan is really easy to find a specific issue but living in Miami is realky hard to find somebody honest and with enough knowledge on this bad boys...
My convertible top went up and down fine until yesterday October 25, 2015. The red light on the switch to power the roof up was flashing. I could hear the electric motors work when putting the switch in the down position then the light went off on the switch. Bought a new switch and relay from import parts store after checking the fluid reservoir. Replaced both now all I hear is an alarm the roof hydraulics are not working however electrical power is going to the electric motor. Now nothing is happening except the alarm when car is in gear. The hard top won't even snap to place. Any ideas of what to do? Like to get this problem solved and hard top back on for summer is over in Ohio all 4 weeks of summer.
