So six days, two tows, two shops, and about 10 hours combined diagnostic time they finally found the problem.............

Two blown fuses.

Both shops claimed to have checked the fuses with a meter but neither had actually pulled the fuses out. I guess this is good to know that our fuses can give false positives and actually need to be pulled and visually inspected.

 

sucks to hear. sounds like an expensive way to replace 2 fuses -_-

 

I wonder who said that on the first reply to this post.................................... Glad u found the problem though :P

 

I wouldn't go back to those shops.. Theres no way a fuse will be hot on both sides if it's blown... And did they figure out why they were blown? Fuses just don't wake up an say I'm going to blow today..

 

were they measuring voltage? cause an open (blown) fuse with read voltage, lol...and for resistance, it would measure the resistance of the rest of the circuit...you have to isolate components and understand the circuit or a multimeter will tell you nothing...

 

.......


But in all seriousness, I feel like those shops probably didn't check ur fuses at all.

 

they probably metered them, and didn't isolate, so it appeared good...as i said, a DMM will read voltage across an open, but it would be maximum voltage, not the actual voltage it should be, incorporating resistance, because with no current flow, there is no resistance, hence maximum voltage, E=IR, and on the ohms setting it will read the resistance of the entire circuit beginning at one side of the blown fuse, ending at the other...so if they were not trained on how to properly troubleshoot electronics these readings would lead them to believe the fuses were good...

i would think if they said they measured it, they probably did, they just didn't understand what they were seeing...

 

The first one was a shop, the other was the dealership. It took the dealership 7 hours to track the fuses. It just goes to show that most shops are too lazy to actually pull the fuses.

I will still go to the same shop though. They do great work. They just missed on this one. They didn't charge me anything and actually covered to cost of the tow to the dealership.

 

that's decent...

 

Yea that is decent.. And crans you can't check ohms with power flowing of course you can turn the key off but than you have to check if it's getting voltage on each fuse than check ohms but that's not the right way to do it cause like you said your not singling out the fuse.. The best way in my opinion is a test light if the light isn't as bright on one side of the same fuse check that fuse
