#162 of 221 2004 Grand Am Lights dimming by bronk08 Feb 14, 2008 (9:26 pm)
Yes I have a 2004 Grand Am and when I am on the brakes the headlights dim and the heater bogs down. As soon as I hit the accelerator it all comes back. I have had a brand new battery and altenator put in and I am still puzzled. My pontiac dealer also checked the grounds to make sure that it was all ground. PLEAS HELP!!!

Replying to: bronk08 (Feb 14, 2008 9:26 pm) I have had all the same exact problems as yourself since I purchased my 2004 Grand Am. I am now going to try replacing the both relays in the car as now my lights are intermitantly going on and off. Major safety hazard. The dealer has checked this car numerous times and never found anything causing this. If this fixes my problem I will gladly let you know. I won't have the relay until Wednesday. Seems to me that if you are having the same exact symptoms there is another underlying cause of this problem. If you don't mind me asking what state did you purchase your car????? I purchased mine in southwest florida. Replies to this message: bronk08 (Feb 17, 2008 10:33 pm) nessa43 (Mar 05, 2008 5:39 pm) bronk08 (Feb 28, 2008 4:14 am)

Replying to: bronk08 (Feb 17, 2008 10:33 pm) I have changed a 10amp fuse in the drivers side fuse panel which has fixed all the problems except when i apply the brakes. I will be changing the relays over the weekend. Sorry I work two jobs and my time is very limited. Hope this helps. Will post my results when I change the relays.

#168 of 221 #1 Cyl. Missfire problem by lowrunner Mar 22, 2008 (12:16 pm)
ok ! what i have is a 1996 pontiac grand am 2.4L dual overhead cam,electronic ignition. (IDI) "Intergrated Direct Ignition". System its running very rough,getting bad gas milage. when i get off the freeway and come to a stop it stumbles and then picks back up. it does it at a stop light also,lacking power.   i hooked up my "OBD2" code reader, and it gave a reading of "P301" #1 cylinder Missfire Detected   #1) Replaced Plugs & Boots and coil housing   #2) i placed a ohm meter between #1 & #4 on the coil tower and it read 5.0 ohms the same between 2 & 3 and no reading between coil and cover Plate   #3) switched coils around to see if it was the coils. still shows #1 Missfire   #4) i checked my ignition module by connecting a test light (at the module) between bat. pos. terminal to the coil(Terminal A) and terminal B or C . when cranking engine light blinks. according to the book tt that should eliminate the module from being bad. but to check for open or shorted circuit in the coil wiring harness. i didnt do that. how do i do that? and where do i do that?   #4) put a ohm meter to no.1 injector, the reading was within specs described in book.   #5) i Disconected the electrical connector to the (IAC) "idle air control valve"started engine and pulled off each injector connector to the injector and there was a noticable difference in idle change      i didnt have a spark tester light so i couldnt test that from what i described you have any advise or instructions besides "take it to the shop"              thank you Replies to this message: egryeyes (Apr 02, 2008 1:28 am)

#171 of 221 Continuous Turn Signal Chime by ttubando Apr 30, 2008 (7:19 pm)
after signaling a turn yesterday my turnsignal flicked off, but as it did the chime started going double time. it kept going untill i turned my car off. i turned my car back on and it started again. it will resume regular chiming when i signal a turn but will then resume the annoying chime when the turn signal flicks off. the fast chime doesnt make any lights flash though. also it will slow or go off momemtarily they resume whenever it pleases. i have had to have my computer replaced twice for corrosion and am wondering if it is the beginning of the same problem returned. (the first time my door chime was sounding when my car was off and thus constantly ran down the battery and the second time my car just plain wouldnt start.)    if it has to go to the shop again, this will be the 3rd time in the 6 months i've had it.
