2003 PT lighting issue

I have an 03 PT and the lights will pulse dark then light when the lights are on. Would this be a bad altinator or bad voltage regulator. I have had the electrical system check out and it checked out fine which means its charging. Am I close with my diagnosis?

Have the battery checked for its acidity level. the alternator might be charging it well but the battery could not store all the charge.

Yes, i have a 2003 chrysler pt cruiser and i just put a new battery in it now my dash, headlights and dome lights flicker real bad?


The issue seems to be common among the 2001-2005 models of PT Cruiser. Changing the battery (from other answers on other years with similar issues) seems to short out things like the lights and the stereo. Some suggestions for fixing it, if you can't find where the electrical wiring for the lights attaches to the battery/computer, to make sure the wires aren't frayed, the plastic housing isn't worn away, and the grounding wire hasn't been severed...then a mechanic should be able to find them for you.

2003 PT Cruiser interior and dash lights not working


If your car's overheating, make sure you have enough coolant in the system. While you're under the hood look for disconnected wires near dash then check your fuse box for broken fuses. Please check your coolant, little to no coolant = a new engine ~$5000!

03 Taurus, battery light comes on. R&R bad alt &


You may have a a/c voltage leak comming from the alternator..If its a rebuilt alternator sometimes you get a bad one ..But make sure all your connections are good ecspecially the small wires coming out the back ..These are the field and sensor wires..Plus make sure all your grounds on the vehicle are not broken or missing..You can have good voltage but it may have a drop going to the computer because of a ground and cause the light to come on

My 03 pt started handling poorly in the front end..feels unsafe, like wandering on the road..suspension feels normal..checked fluids and there fine..engine light stays on


I had the same issue with my lincoln LS. You may need an alignment. Many shops off the service and the work is usually an hour or so. This will help with drift feelings and the wondering you mentioned.

Good luck and be safe

Battery lite came just replaced the battery and chkd alternator (it was good). I jump the battery and trk stays running about 10 mins and dies. Could it still be the alternator?


i might be a bad altinator but i would double check your battery. a bad battery will kill a new altinator. does the battery light stay on? if the battery light on the dash is not on you may have another problem...

Check all grounds ie motor to body ground strap connections for corossion, battery to motor ground, battery to body ground. You have to check under bolt to see if there is coeossion. Bad grounding can cause all sorts of electrical problems

Battery light on 2003 intrepid came on


if the charging circuit is low, then it appears that your alternator is going bad....

Battery terminals, when car is off, should read 12V+-.2V. When the car is running, terminals should read 13V-14V=-.2V

Headlight wont work


Did you try swaping bulbs from left to right to see if you got a bad bulb? Did you check voltage at the plug where the bulb itself plugs in? Test lights don't really show you the whole picture. Invest in a Voltage meter.
