I plugged in the unit today ran it up and down motor only worked as should I have the unit on Tore B page and wondering the large yellow waffer I cannot recall what it is called but used to take up the inrush of current if it got hot enough would it stop the spoiler from rasing.. a thought . the 3 caps you took them out of the pcb and checked them and found to be bad good work
Randy, intermittent faults are the hardest to fix. When I get a box to repair, I first check it’s actually faulty. If it is, I just replace all six capacitors and the two relay drive transistors. They are all so cheap, it’s quicker to do that. Did you replace the capacitors or just refit them.

This may be a *very* dumb question but what voltage are these capacitors?

It will depend what your local supplier has in stock. My 220uF is 16v, 47uF is 25v and 4.7uF is 50v. I’d like more margin for the 16V but that was the only local option. 25v and above is fine for a car. ​​​​​
