Question there is a circle light that went on a couple days ago. i dont have my mannual so i dont know what it is. do you know by any chance?

Probably complete failure of the I/P dimmer

Knocking : ticka ticka, clatter, or clunka clunka? Ticka may be lifters, timing, spark, or other not too serious. Clatter may be oil pump. Clunka -serious lower end rebuild. Dont run or might destroy chance to rebuild

You might just have a wire loose somewhere. My 96 Cadi did that a couple of times lastyear, then it was fine. Hasn't done it since.` So, who knows! Sorry, not much help to you.

Check your tire pressure with a tire gauge, under $2.00, or ask gas station attendant to borrow thiers. Check with your owners mannual or inside the drivers side door should have the PSI your tires should be at. Do all four tires and if you have a full size spair it might even register this. Good Luck!

The dash lights take a feed from the tail circiut,may be a corroded connector,pinched wire somewhere.The blower problem likely not related,maybe bad blower motor or resistor.

Any time you get any check light, you should
be at a repair in a couple of days, or at least
check for codes. Still need it diagnosed and
repaired in a week

Otherwise you waste gas,polute the air or could
cause some damage,as you don't know what the issue
is that set the light

The fact the check light went out, doesn't mean
the problem went away.

Don't clear any codes you find,their needed to diagnose
the system faults

I ran into the problem and it was corrosion on the battery terminals. on the inside against the battery. also check the the terminals for good connection.
Stay warm

maybe you need to have dianostics done on the inboard comp

I have the same problem with my 02 intrepid es. It started happening a couple months ago while Im driving. They just flash a couple times every once in a while. Its annoying and I dont know whats causing it. Just wanted to let you know you arent alone lol.

If signal lights are working, probably a failing headlight switch. Even though fuses seem OK, you can try replacing the appropriate fuse.
