510 Resistor Help Needed (truck Temp Console)

Recommended Posts

Hi everyone:


I lurk often but haven't posted much...


I thought I would post this in hope that someone may be able to help me. I have a Tacoma truck and my temp/compass read out deal stopped working. I got on a Tacoma forum and found a fix (or so I thought). Apparently the 510 resistors (top photo on right side) have a tendency to lift off the board. The fix was simply to solder it back down which I did (bottom resistor on right side) or at least tried to do..


Put it all back together and it worked. Problem was that after a week or so it stopped. I took it down and apart and messed with the solder edge and it worked again, but only for about 4-5 days.......


Now I cant get it to work again. I even hit the other 3 edges with solder to be sure they were making a connection. No good.


I hooked up the power and pressed on the resistors and they got hot quick... but the display did not come on...


How would I know if one of the resistors is bad?


Why would it work for a week and then stop?


Can I replace them?


Can/would one of you high tech guys trouble shoot it or fix it for me?


Thanks for any help..

My Honda crv does the same thing, tried to reflow the solder on all 3 resistors too, mine comes on after about 25 mins of driving lol or if I bang on dash lol

measure the ohms of the resistors if you know your colour code you need meter to do it and it could be a cold solder joint that make them get hot give me the colur and I tell you the ohms of resistors the last ring is the tolerance if it has one if not there no tolerance
