your diy helped to solve mine and also I shared your video to del owners and portuguese community. most of them did not know the cause of problem, so they won't need to buy another 30yo cluster lol
I had the exact problem, speedometer reading very low if at all. I followed these instructions and it seems to be working now. I'm a ham hands with little soldering experience and I was able to do it. A couple things to note. When removing the cluster, the large blue connectors on the top have small clips on the top that are hard to see. Took me a bit to figure it out. Put a small screwdriver in the very top part from the front and gently pry up a bit and the connector will come right out. The desoldering part was tricky for me. Even after removing most of the solder the old capacitor was stuck. I used a tweezers and pulled down gently on the capacitor while heating to remove it. Good luck, this is the best video by far outlining the process.
Hey there, how did you know this was the issue? My speedometer stopped working just reads 0kph. But, it used to work intermittently, after start up and driving a few meters, I would flick the cluster and the gauge would start working. I've tried replacing the VSS and the connector to the VSS, but this fixed nothing. I also don't get any CEL codes. I thought perhaps to start off by checking the signal and ground wires to the VSS, but couldn't find anywhere what how to read the signals and what values to get.
Just replaced the 6.8 uf cap with a 50v one and it fixed the speedometer in my sons 1993 del sol that hasn't worked for several years now. How did you find the capacitor that was bad. Mine did have a little leakage on bottom but top was not swollen. Problem is, it didn't fix cruise. I've replaced speed sensor and then fixed speedometer be replacing the cap, but still no cruise. Light doesn't come on when pushed.
so what was the original issue? Mine reads slowly (off by about 5-10-15 mph) depending on the temperature. I was thinking it may be the capacitors too.
