#11 of 30 96 Monte Carlo- electrical? by montecarlolove Apr 07, 2008 (2:11 pm)
i have a 96 monte carlo , Ive had it nearly 2 years and love it , but within the past 6 months ive been having problems with it acting funny. At first it acted as though the alternator was going out, then the battery died, now im finding that the battery connections keep comming loose. has anyone else heard or noticed this problem? we also began to wonder if the ignition switch was going bad , because i would go to turn it over and it would hesitate for a few seconds and then try to turn over.
#12 of 30 problems with lighting by robbus Apr 12, 2008 (6:02 pm)
I just lost my tail lights, side marker lights and dash lights-brake lights, turn signals and headlights all work fine-any idea what could be causing this? All fuses inside are good and the car just passed inspection in January-Would appreciate any ideas!! Thanks! Replies to this message: mckinnon34 (May 02, 2009 4:52 am)
#13 of 30 Electrical issues by rvac99 Aug 28, 2008 (8:18 am)
Hello Monte Carlo owners. I'd like to share with you some problems I have had with my Monte. My AC and Cooling fans stopped working on a long trip to Florida. After $80 at the dealer they told me it was the PCM and it would have to be replaced and reprogrammed. I checked all the wires and have installed toggle switches that bypass the PCM and I can manually control the fans and AC. I asked a master mechanic online and he said if I could live with the switches that was the cheapest way to get around the problem. I get a trouble code for the cooling fans but I still got it inspected anyway (check engine light was on). My car shifts hard when the fluid is warm and I notice bubbles in the fluid. Checked it because I thought it was low. The bubbles make it read high. Also lost use of my heated seats and rear defroster. Working on those problems next. Probably have more toggle switches to install. Let me know if you have any insight on my problems and I'll do the same for yours. rvac99cox.net Thanks.

#14 of 30 dead battery issues by blue02ss Nov 22, 2008 (11:03 am)
I have a 2002 SS with 69K miles that I bought with 50K earlier this year. I recently started to have issues where the battery will go dead for no apparent reason (no interior lights on, etc.) I had the electrical system tested and the dealer found no parasitic drains. I've narrowed it down to when I drive it one day, the next day it will be dead (or the battery will be depleted enough that it won't be able to start). However if I put a battery charger on it and let it sit with a full charge, it can go up to a week and a half sitting without a problem, then will start right up. I've replaced the battery three times with different brands to no avail. Any thoughts?

Replying to: rvac99 (Aug 28, 2008 8:18 am) Any luck with the heated seats and rear defroster? Got the same issue on my 2006 LTZ Monte. Also the remote start does not work and the car does not heat up while idling. 5 below zero and this all is a pain.
#16 of 30 2000 monte carlo by dancermom4 Mar 23, 2009 (7:53 pm)
I have a 2000 monte carlo and for some reason the headlights aren't working properly. They come on when i turn the car on and then after I drive for about ten minutes they shut off and then a few minutes goes by and they come back on. This is really annoying so if there is anyone who has any idea what the problem could be please help.

#19 of 30 No heater or a/c by classicman Apr 25, 2009 (8:25 pm)
Has this happened to anyone. Heater and a/c system out on our 2000 monte carlo LS. For several months now the heater would not work (no vent control no blower- completely dead), until the car had been started for several minutes. Then it would mysteriouly start working. The minutes became longer until the heater does not work at all. The cruise control and overhead console also follow the same pattern. Checked all fuses and relays associated with the problem 0k. On one occasion on a road trip the cruise control A/C heater was out for about 40 miles. I heard a relay close, sounded like it was behind the instrument panel and all began working. Please help.
