sounds like a alternater problem. with car off battery voltage should be at least 12.6 or better. less than 12 volts battery is bad. when running at battery, voltage should be at least 13.5 to 14.2 or better. take negative battery cable off while running, if car dies its the alternater. Good-Day! you can take alt, to any auto parts store to get it tested. advance,auto zone, etc.
stabilitrac is from balljoints prob on tire rods of sway bar and altonator runs at 14v and batt runs 12. for it to be dropping to 12 you need to run to auto zone n they can check your alt. or while its runnind take your batt post off batt n if it keeps running your alt is good and if it dies out rite away alt has to be changed
even thow alt is new it could be bad,,,the fan runs off a temp sender,,if it is bad it will not turn fan on,,,on fan runs off temp sender one run off your a/c or defroster,,if u get a chance to go to auto zone or advance auto they can ck out your charging system for free,,,, hoped it helped,,
test and check battery and or connections to and from alternator also check the connections for the abs sensors may have a loose or damaged connection if looks good than have car scanned for trouble code [even with light out compute still stores code] some auto stores such as auto zone / advanced auto scan for free check ur local area the code will give u a start point towards fixing ur problem good luck
You named the three items I'd look at first. get a manual (chilton or haynes are fine for this) and a digital multimeter. Run the tests on those and likely you will find the problem. You can also remove and clean the IAC valve and passages but do not turn the valve while cleaning or it may not seat correctly.
If it has injectors it has a ecu, if it has an ecu it has a diagnostic port (normally under the drivers/passenger dash) if you look down at seat botton level you should see a small black port) You can go to any auto zone or parts place and they will scan it for free. You may have a head gasket issue with overheating or your cooling fan(s) may not be turning on. Check the codes first
