Question about 2002 Jeep Grand Cherokee
The lights began flashing intermittently on and off ???? . Wouldn't be a relay problem , a stuck relay the light's would be on all the time , wouldn't be able to shut them off . I would think a control module or secruity system . The BCM - body control module controls the lights . The Headlamp switch is a input to the BCM , the BCM does energize relays to turn on the lights . More then likely the automatic headlamp light sensor which is an input to the BCM could be the problem . Taking the vehicle to a qualified repair shop an having the BCM checked for DTC'S - diagnostic trouble codes is your best bet , Don't take it to autozone , advance etc... as they can not access these codes .

Try unhooking the daylight switch. I had the same problem with a thunderbird. I unhooked the switch, it kept the battery charged and I installed a new switch ... no more problem. Also check and see if one of your headlights are out or very dim. My 02 cavalier did the same thing because of a bad headlight. These are just some places to look at .... good luck.

Check blower fuse, relay and power at blower motor harness terminal. Check for proper grounding at dashboard and body as well. Yo
good lucku can run a hot wire to the blower motor and touch it to the connector spade to check if blower itself is OK. There are other components in the system, but this is a good start! Don't forget...fuses blow because there is a problem elsewhere. If you replace one and it blows again, there is something else wrong!

The body controller for some reason has lost it's setting most likely. The dealer can reset with their "Star Scan" diagnostic tool. Many settings such as flash on lock or horn sound on lock can be turned on or off.

sounds like a battery or ground connection problem , disconnect and clean the inside of the battery cables and the posts,tighter securely . If that doesn't do it remove the other end of the negative cable and clean the cable end and the metal that it bolts to.

I had the same problem a year ago. Turned out to be a little more complecated after time. It started with the relays then I started keeping track of voltage. This is after the fan and lights were working intermitently. It turned out to be a faulty voltage rectafier. Some guys were close on other fixes I still don't trust my fan sensor. I think i have a bad thermostat it lets the bike run too hot but the fan sometimes lets me down. Put the by-pass switch for energency. O by the way check the Rectefier connections at back of the bike may have oily substance some say it is oil that travels up the wires I don't know that but mine was nasty I bought a new rectefier and cut the wires their direct now never had problem with relays so far. I know its weird the bike still cranks but im just saying thats what i went thru for months

[Information] For a 2002 Toyota Camry, the Daytime
Running Lights (DRL) operate utilizing the High Beams (inner Lamps closer to
the center of the vehicle front) at a reduced power.
[The troubleshooting process:] Review the Owner's Manual and ensure the test
configuration matches the following criteria:
1. According to the 2002 Toyota Camry Owner's Manual (Check your Owners Manual):
"The DRL system will make your headlights come on at a reduced brightness when:
The light switch s in the "DRL" position.
The ignition is on with the engine running.
The headlight switch is off.
The parking brake is released."
2. Set the Test Conditions according to Step 1 above.
3. Check the headlight bulbs to ensure they are not
burned out. If one burns out, there is a fair chance that the other would have burned
out at the same time. Replace as necessary.
In this case, if the high beams operate, the DRLs should also operate.
4. Test the system, ensuring the step 1 conditions are set. (Engine running, Multi-function Switch on Turn Signals in "DRL" position, headlight switch off (repeating what the manual says -- it should be obvious that in the "DRL" position, the headlight switch should be off / do not have the switch positioned to "High Beam"), and the Parking Brake "off").
5. If DRL lights do not work, check the engine compartment Fuse and Relay Box. there is a 5 Amp DRL fuse -- replace it with the spare. Test (step 4).
6. If it does not work, swap around or replace relays -- there are three (3). Any one of them could be bad (stuck or burned out). Test (step 4).
7. Other less likely possible issues could be that the Multi-function Switch is broken or a connection / wire is broken. [Beyond the scope of this process.]
My problem was that the test configuration did not have
the engine running and parking brake off - Step 1. Problem solved with much
thought, repetitive tests on the vehicle and going back to the basics -- what
does the Owner's Manual say and where are the applicable fuses and relays
