So today I received a ProgRama rebuilt cruise control unit as part of a trade. I was very curious as to what exactly they did. ProgRama is one of the big repair companies that Ive seen listed on parts websites, they also do climate control units and whatnot.

Below is some photo comparisons. The ProgRama unit was originally an 002 545 32 32 unit. They re-labeled it as an 002 545 91 32. I've taken pics of: an original untouched 002 545 32 32, the ProgRama 002 545 32 32 and one of my repaired 002 545 32 32.

Here they are for your viewing pleasure. I'll note the difference at the bottom of the post.

It looks like one of the output transistors went out on the ProGrama unit. Its pretty easy to see the blackened spot on the one pair. It'll be interesting to see how it repairs up. Those will probably end up being replaced. You can also see that they did not replace all the electrolytic capacitors. The four axial type at the front are original. You can also see they did not use any protective coating on the solder side of the board. Everything else looks original. They did re-solder the back side of the unit, mostly. You can see a lot of flux from the solder all over the place.

Its interesting to see how the word rebuilt is thrown around.
