Dmurph2016 Posted June 25, 2021 Author Share Posted June 25, 2021 I’m going to pickup a new switch, and see if that makes a difference, dealer wants $100 bucks for the reostat, I was originally thinking maybe it was not the switch but I doubt all the Lights are out, we will replace the sketch and see what happens. If it’s not the switch how hard is it to remove the cluster?

Joey Mack Posted June 26, 2021 Share Posted June 26, 2021 was there 12.6 volts at the switch plug ? Quote Link to comment https://www.bigmacktrucks.com/topic/67067-are-these-2-issues-related/page/2/#findComment-475835 Share on other sites More sharing options...

At the plug It looks like I’m getting 11.6 (with the truck off, I’d that makes a difference) Quote Link to comment https://www.bigmacktrucks.com/topic/67067-are-these-2-issues-related/page/2/#findComment-475950 Share on other sites More sharing options...
Joey Mack Posted June 27, 2021 Share Posted June 27, 2021 Thats low, are the batts good? during this test? I have simply put a paper clip in the plug at the dimmer switch to see if the lights come on "Full bright"..

You put a paper clip in the plug like a jumper? I’ll have to try that, see if I have a paper clip somewhere. edit truck on getting 12.9v to that plug Edited June 27, 2021 by Dmurph2016 Quote Link to comment https://www.bigmacktrucks.com/topic/67067-are-these-2-issues-related/page/2/#findComment-475952 Share on other sites More sharing options...

Onyx610 Posted June 28, 2021 Share Posted June 28, 2021 That’s a circuit breaker, you can test it with a volt meter or switch it with a known good one and see if that fixes it.

I was at the dealer picking up my speed sensor, and I was talking to the guy at the counter, he brought up a good point. If that circuit breaker was bad, I wouldn’t be getting the 12v at the plug, I told him I jumped the plug and still no lights, he said there’ a good chance that the bulbs could all be Burnt out. So I think I’m going to try to figure out how you take the cluster out so I can check the bulbs Quote Link to comment https://www.bigmacktrucks.com/topic/67067-are-these-2-issues-related/page/2/#findComment-475995 Share on other sites More sharing options...
Onyx610 Posted June 28, 2021 Share Posted June 28, 2021 I was gonna say, most likely you have some bulbs out in the dash. Between vibration and age it’s a good chance.

Dmurph2016 Posted June 29, 2021 Author Share Posted June 29, 2021 Does the cluster come out easy to change the bulbs? I don’t want to just unscrew dash parts and pry possibly damage something.

Dmurph2016 Posted July 6, 2021 Author Share Posted July 6, 2021 Does anyone have instructions on how to remove the cluster to replace the bulbs? I can’t seem to figure it out, I took some screws out but it was the bezel that came off.

Joey Mack Posted July 7, 2021 Share Posted July 7, 2021 You take the cluster out of the dash... unplug it... then take it apart and change the little tiny bulbs.. I think the are #68 bulbs.. wicked small,,, I beleive they are in a little socket that turns a 1/4 turn to remove/install them... Just be careful handeling the circuit board... its about $1000.00 if you break it.. You may be able to remove the bulbs from the socket or you will have to buy the bulb and socket complete. I used to get these from MACK... I'm sorry that I dont have a picture of the bulbs... jojo 1 Quote Link to comment https://www.bigmacktrucks.com/topic/67067-are-these-2-issues-related/page/2/#findComment-476446 Share on other sites More sharing options...
Joey Mack Posted July 7, 2021 Share Posted July 7, 2021 Ok, I forgot that I had some bulbs.. Forget #68,, i think those were for the strip that has the turn signals and low air and such, like in an MR or LE... I believe the bulb pics I sent are correct. Just look to see if these bulbs are in the circuit board...

Mark T Posted July 7, 2021 Share Posted July 7, 2021 Weren't those lights black ( or green ) in those ? Same tiny bulb in twist in base. If I remember correctly, all the screws that hold the gauge panel in the dash were #27 torx then the harness plugs had the squeeze to release tabs on them ( and only go on one way ) Quote Link to comment https://www.bigmacktrucks.com/topic/67067-are-these-2-issues-related/page/2/#findComment-476449 Share on other sites More sharing options...

I would rather look stupid asking questions then go and just pry stuff apart and damage things, because it sucks when you try to go fix one little thing and it ends up costing you a bunch of money to fix a bunch of other things that broke in the process. With that said, I’m not sure if the truck just decided that it wanted to cooperate or what, but I went to get it inspected and as the guys putting the sticker on the windshield I see that the dash lights are all working, hopefully they stay working. edit* I guess I jinxed myself, just went to check something in the truck and the gauge lights came on, then you could hear a click and they shut off and won’t come back on.

Onyx610 Posted July 9, 2021 Share Posted July 9, 2021 Sounds like a relay or circuit breaker 1 Quote Link to comment https://www.bigmacktrucks.com/topic/67067-are-these-2-issues-related/page/2/#findComment-476565 Share on other sites More sharing options...

I tried a different circuit breaker, same result no gauge lights. Not sure if there’s a delay for the gauge lights by themselves. I may have to end up taking the cluster out and looking around.
