My 92 500sl benz converible top is starting to act up going up and down very slow or get stuck

Lubricate all of the pivot points with something like WD-40 or a dry graphite lube. Check to verify that the convertible motor/pump is receiving steady power during operation. Make sure nothing is binding the convertible mechanism. Our reference shows your convertible system to be electro-hydraulic, so also check the pump operation by verifying constant output pressure.
