Stagea c34, Cluster errors

[TheKenso]

Hi ther, i have a problem that came after i changed my baulbes in my AC, replaced them with LED's and my cluster started messing up, Fule and Engien heat is always on max, spedo don't work, and RPM bounces on 500-1000rpm on idel and under full pupp it only goes up to 3000rpm, and the KM on the car reads 999999.
Changed back to my normal baulbes and cheked the wiers to chek if ther was any faulty wiers behind the AC unit but coudent finde anything, changed back to my old Baulbes and it stil dosent work.
I alsow blew the fuse for "Tail L" wile replacing the baulbes and have replaced the fuse.

So, what can be the problem? Can i have messed up the cluster and blew a resistor? is ther a relay that have exploded?
I have had the AC unit and CD player out 6-7 times and tried to turn the key on and off, and sometimes it works like it shoud somtiems it just a bit faulty shoing way to hige RPM and the wrong KM (shows about 116k the car has traveld 160k)

Sorry if the post is messy, im not always that good at explaning things

See if you can clean the connectors that go into the back of the cluster. Look for brittle solder and touch up with a soldering iron.

Check your battery terminals for cleanliness and tightness.

You may have stored faults in your ecu, check and erase. The cluster alters the speed sensor signal for its own and the ecu's use. check the Large main connector is inserted correctly. Good Luck.

And, the tail light fuse may also provide the dash power, so it is possible something was shorted and damaged in the new dash when you installed it (or it had a pre-existing problem you didn't know about)

i have chekd wiering, cheked error codes and pulled out the cluster but dident finde any errors anywher, and  i feel its wird that its just some times it's messing up.
alsow changed the battery but stil no luck, is ther a way i can manuly test the Cluster to chek  if the problem lies tehr?

Stil havent found anny error after about 6 months, stil off and on if its working, thinking it migth be a Relay, anyone know if ther is one? and wher?

Hey did you ever sort this issue? I currently have the exact same issue in my Stagea.
