Quick answer. A 2015 Jeep Grand Cherokee SRT with the 6.4 V8 came in for a blower motor resistor and an electrical diagnosis. Our tech spent two hours on it, $300, and found a frayed wire. Fixing it was bigger than what the owner had approved. So the tech stopped and asked for a new yes.
Key Points
- The job was an advanced electrical diagnosis and a blower motor resistor.
- Two hours of labor at $150, $300.
- Our tech found a frayed wire.
- The repair was bigger than the approved figure, so work stopped for a new quote.
- The Jeep showed 134,355 miles.

A Resistor That Was Not the Whole Story
Blower trouble on a Grand Cherokee often gets blamed on the blower motor resistor. It is a common part to fail. So that is what this job was written up for.
But the job also had an advanced electrical diagnosis on it. That is the right call. A resistor that keeps failing can be a sign of a wiring problem feeding it.
Our tech had two hours to find out.
What Our Tech Found
The tech's finding was short. Diagnose frayed wire.
A frayed wire is a real problem on any car. Bare copper can short, run hot, or cut power to the part it feeds. Swap in a new resistor and leave the bad wire, and the new part can fail too.
Tracing a wire on a Grand Cherokee means pulling trim. Harnesses run under the console and behind the dash. That is why electrical jobs bill by the hour.
Why the Tech Stopped
The owner had approved two hours. The fix for the wire was bigger than that.
So the tech stopped. That is our rule. When a job grows past the number you said yes to, you get a new quote and decide again.
We do not have the end of this one on the record yet. We are not going to pretend we do.

Frequently Asked Questions
Why does a blower motor resistor keep failing?
Sometimes the wiring that feeds it is damaged. On this Jeep our tech found a frayed wire. A new resistor alone may not last if the wire stays bad.
How much is an electrical diagnosis on a Jeep?
This one was two hours of labor at $150, $300.
What happens if the repair costs more than I approved?
The tech stops. You get a new quote and decide before any more work is done.
Can a frayed wire cause other problems?
Yes. A frayed wire can short, get hot, or cut power to the part it feeds. It is worth fixing right.
Supercanic tip: If the same electrical part fails twice, do not just buy it a third time. Ask for the wiring to be tested. Call us at (951) 904-2477.
Electrical Gremlin?
We trace the wire before we sell you the part, and stop if the job grows.
