I did this, and like some others, I didn't see any broken wires. But, also like some others, when I reassembled everything the gauge seems to work much better. Thanks!

 

The electronic mat behind the gauge cluster for the same style where would i find a new one mine melted?

 

I will be trying this.
Noticed my temp gauge on the 87 4Runner reading hot when cold sometimes.

 

keep in mind that the temp gauge sender could also be a problem for some with this issue and it's the sensor with the spade connector on the lower intake between cylinder 2 and 3 smack dab in the middle of the lower intake right up next to the valve cover. If you put a lead on the wire end and ground it to the chassis or block the temp gauge in the truck should turn all the way to hot if the gauge in the truck works. that tells you the sender unit is bad not the gauge. I had that issue where mine, it was jumping around and reading at only about 1/4 low temp most of the time, I tested it and the result pointed at the sender not the gauge then I got a replacement sender at the junkyard and all is well. Actually for anyone planning to tear in to their cluster it's was easier to test that the gauge is good or bad from the wire to the sender unit on the intake than it is to bust open the dash to find out that's not it . good writeup on fixing the cluster though I'll bookmark this incase my gauge end ever breaks on me.

cheers.

 

Thanks


Excellent write up and pictures. Kudos. Can you tell me any links to removing cluster. Everytime I start I get stuck trying to find out how to get to the Speedo cable

Thanks

Hello, old threat but hopefully someone sees this. Great info on this repair, took my cluster apart, found the 3 nuts for the temp guage not as tight as id like, no wires broken, but i did notice when i put my screw driver on one side of the winding, my guage will go up to over half way, does not do that on any other side of the winding. Is that telling me thats where my problem is?

 

Great write up!!! I"ll have to try this with my instrument panel, for years it has been behaving as you mentioned. Can't wait to have a temp gauge I can trust!

 

I took apart the cluster for my 91 sr5 and while the gauge is slightly different it is the same repair.

 

on the screwdriver moving the needle, is your screwdriver magnitized maybe?

 

I wish I'd seen this thread before i replaced my altimeter with gauges. I do keep a better eye on the engine vitals with the new location.

 

sorry for the late reply, but I don't remember which screw driver I was using, the screw driver itself was not magnetized, but I may have been using my snapon mini screw driver that has a magnet at the end of the handle

 

There's our culprit. This wire should be soldered onto that grey pointy peice below it. Check each wire carefully for breaks, your broken wire may not be the same as mine:

Can someone tell me what is meant by "grey pointy piece" in the picture associated with this info?

Appreciate it
JC
