04 jeep grand cherokee. Blinkers, heater and ac, high and low cooling fans....all quit working at once. checked fuses and relays under hood, inside fuse box good, repaced ignition switch, checked
checked means what, gandering at them
checking real is measuring them, with an OHM meter
fuse that look bad are in fact bad, but look ok can in fact have hair line cracks humans cant see, for sure old folks.
what works and what not is the TOP CLUE here,
1:heater blower dead, blower key word
2: ac DEAD sure it is with #1 PCM logic does that.
3:blinker something , dead, stuck on, one works 3 dont what?
4: high low cooling fans, underhood or dash?
5: does car drive, omg, does it? and not stated !!!!!
6: does car drive at night, headlamps work.
7: air bag on , driving? when? it will just key on, as do all warnings as s self test.
8: anything else work or not work , radio, wipers, and all things.?
9: does engine crank ,ok fast, sounds strong?
10: are head lamps dim.????
11: did you skip things that are dead in your report.?
ID bet you never scanned it , right.
what does GOOFED mean.???? sounds scary that.,!means hacking to me.... why say this.? with no photos show if damage.
you cant fix modern cars lacking a scan tool.
I can do magic with my tools but you cant.
i have a full lab. (lab scopes and things you've never seen)
but a scan tool is dirt cheap and is a MUST.
IF the cars power distribution system fails
even a $10 voltmeter can find this, got one?
lets see. the list
1: fuses good, not the gandered at way.
2: battery lugs ok, not corroded.
tell more, get more, lots more,
