Saab 900 convertible hood fault
Can anybody help? My Saab 900 convertible (M reg) has just developed a fault with the hood. The hood hasn’t been used since early September but was working fine last time used and the car is used daily. First of all, it requested that I “check the latches,” many times over. I attempted to raise the hood to check the tightness of the latches but there was little response once I engaged the electric hood.
Took it to my uncle who lives seven miles away, during this journey, the rear windscreen lifted up about 3 inches, which made me jump, as suddenly it got a bit draughty on board! When I finally got to my uncle’s, you guessed it; he pressed the switch and the electric hood motors jumped into life. The hood completed the cycle from being closed, to fully open without fault. This consisted of the rear windscreen lifting up, then the plastic cover lifted up fully, then the roof and windscreen moving into the boot and then the plastic cover finally coming down to complete the cycle.
However, when we tried to put the roof back on, the plastic cover lifted up correctly, then it brought the hood back over my head correctly, at this next stage it is going wrong. It should at this point bring the plastic cover down for the rear windscreen to then park itself on, instead it is trying to place the rear windscreen down first. My uncle did notice that on one of the sensors, top hood motor on the driver’s side (off side) that the wires going into the sensor were once cable tied, this tie has been pulled down along with the sleeve revealing the wires. Could this sensor possibly need replacing or is it just a red herring? We have cleaned all the visible sensors and motors and have now run out of ideas. Can anybody help please?
