CNY_Dave Posted August 18, 2014 Share Posted August 18, 2014 I ask if all those things are on the same fuse, but am pretty sure they are not.Drove the car, everything worked, parked car, got in, no dome lights, no radio, tripmeter had forgotten its mileage, clock had forgotten the time, heatercontrols had forgotten their settings.Instead of 2 beeps from locking with the fob, and getting a chirp after 3 clicks, it locks the doors but gives me 5 chirps.Were it not for the fact the radio does not work at all I'd guess simplyit's the 'backup power' fuse, which isn't labeled as such and I haveonly checked the 15A radio fuse so far (it's good).Would you expect the radio to not work without the 'memory' 12V supply?

CNY_Dave Posted August 18, 2014 Author Share Posted August 18, 2014 The memory for radio settings, last heater settings, and trip mileage all need +12V with the key off, so I assume that would be fused somewhere.. I'm really hoping it's not something like what you mention. Quote Link to comment Share on other sites More sharing options...
heartless Posted August 19, 2014 Share Posted August 19, 2014 how old is the battery? there should be date on there somewhere, either as a sticker with month/year or engraved right into the casing. Most batteries are only good for 4 or 5 years, and the more electronics the car has, the shorter the life of the battery My brother/sis-in-law have a Chrysler Town & Country minivan that goes thru batteries every couple of years - it has the remote opening doors, rear dvd, all kinds of electronic goodies.

CNY_Dave Posted August 19, 2014 Author Share Posted August 19, 2014 It was fuse #2 in the engine compartment fuse box, labeled 'cabin' something or other. Turns out the radio indeed does not work if the memory backup supply isn't connected. 1 Quote Link to comment Share on other sites More sharing options...
CNY_Dave Posted August 22, 2014 Author Share Posted August 22, 2014 CRAP. Fuse blew again, it might be the rear-hatch switch wiring although I did open the hatch after replacing the fuse.Anyway, now the Security light is flashing, and the cruise light in theswitch comes on but cruise only works for about 10 seconds.I am searching but not finding a thread where this was a symptom.I have to drive about 8 hours tomorrow, all freeway, and the cruise MUST be working or my back will be wrecked!
