a fusible link will be located where you could get to it if it was going to be a problem .. but stuff happens so it could be something like rodent damage or a pinched wire during assembly .. have you had any work done on anything lately that would require taking things apart under dash or hood new radio you are on the right track perseverance and logic are going to sort it out. you just need to start on one end and work methodically to the other dont make any assumptions .. as you know ... good luck! the switch tests ok at the dash. i got a wiring diagram from a book at the library. it shows two wires going to the blower motor - black & dark green - which dittos what i saw when i put in the new blower motor. however it also shows a splice in the dk grn wire with a black/tan wire in there somewhere. is this a fusible link and if so could it be the culprit and if so how far up into the dashboard nether regions do i have to look to track the sucker down karl .

rerikss@bellsouth.net says... paul jensen wrote went to a local drag strip last night. first time in many many years. it was an open night - pay 15 bucks and jr. could run the quarter mile in daddys borrowed lexus. anyway in the middle of the evenings events a guy showed up with a brand new 04 chrysler 300. great looking car but looked a little funny staging next to some of the modified mustangs and camaros. the guy made about 4 runs with times consistently in the mid 14s. certainly wont win any races but not too bad for a big heavy luxury passenger car. hemi had to be. i thought itd be in the low 14s though. jeff if i recall his best was 14.3 worst was 14.8. speeds were all 100 mph+ unmodified stock hemi. eisboch if hes running 100+ mph hes got traction problems or it the weird drive by throttle it and our trucks have is making it launch too soft. with that speed he should be in the 13s. bdk dont forget now that has that esp traction control on it.. btw- i may be in error on the year - it may have been an 05. not sure they put the 5.7l in the 04s. eisboch .
