I have a 94 grand am se coupe today when we took out the stereo that was in it to put a new one in something went wrong lol. Easy on me im a single woman tryin to do this on my own. Anyhow I hooked up the new stereo following the wire lays out matchin colors etc. Taped up the twisted ends together and tried it out. It worked! So I went to mount it in got it paritally moutned in tried it again and it didnt work. So my friend brought his tester over and checked fuses. He said it seems like there is no power getting to the radio. But on a side note after the radio stopped working my interior lights stopped working, and my abs light came on then later in the day my check engine. My brother fears there might be a short? If you can just please point us in where to start id appreciate it as I surely cant afford to pay a mechanic to do it

Well, the first place I would start is to completely unhook the radio and ensure now wires are touching that are unhooked. I am guessing you cut the wires or they were already cut? Otherwise, a radio wiring harness is a much better way to go then cutting the stock radio wire harness.

Now that the radio is out of the way and all wires are completely insulated and not touching, check all fuses inside and under hood as well.

It sounds like when you pushed the radio into the dash, some of the wires that may have been a little bare have touched and blown a fuse or shorted out.

Not all vehicles have fuses under the hood. If it does have fuses under hood then it should be in pretty plain view. Usually a black box located in one of the corners of the engine compartment. Most common place is next to the battery. Again, not all vehicles have this though. So don't look too hard, if it isn't there it isn't there ;) Just let me know what you find out in the morning and I will follow up.

Ok out in the freezin cold lol I checked all the fuses again and found one that was out so I replaced it and voila the lights work again and I used wire nuts on the radio wires when I reconnected it and bam they both work but alas my abs light is still on. It never was on before and the car wasnt moving when it came on. Anyway to reset it? Or only a mechanic can do this?

Glad you got it workign again. It is unusually warm here in Kentucky hehe.

You can reset the computer by disconnecting the ground cable from the battery for 15 - 20 minutes. Please note that this will reset the entire computer system. So your radio and other settings will lose their memory as well, so you will have to set them to your preference again.

Oh blueeeeee! I have another question. Everything that was wrong is still fine however I had a friend change the oil and filter and since then occasionally the oil light will flicker off and on briefly and randomly my check engine light will come on then stay on. However when I shut off the car for a period of time and start it back up its not on for awhile again. Upon first changin oil the pressure was good and the guage stayed around 40. Now it has dropped and holding at 20 all the time.I checked the oil its full? Any clues?Ty xoxo

Hello again.

Well, I would first go to an auto part store and get the code(s) from the engine light whenever it is illuminated. Could be a sensor, could be oil pump, could be several other things. Engine code will point us in the right direction quickly.

It could just be the weight of oil you used as well though. As the oil warms it is "thinner", meaning that it flows more easily and is closer to the consistency of water. The bearings on your engine use a film of pressurized oil to maintain a gap between the crankshaft or camshaft and the block or rod. That gap is initially quite small and thinner oil is used. As the engine wears it becomes necessary to use a thicker grade of oil. With your vehicle having 150,000 miles on it, you may need to adjust the vescosity of the oil you are using. Same brand, just different weight/vescosity i.E. 10w50 instead of 5w30.

Post those codes and I will follow up. In the meantime, as long as there are no unusual noises coming from the engine then it is being lubricated well so no worries there.

Hope this helps.

Ok so I checked the oil before leaving this am and it was a tad low so I added about half a quart. Drove it maybe 15 minutes and the pressure guage dropped to just above the red line while driving and at idle all the way to 0! And as I pulled in garage at house a light came on saying check guages? Ugh dang I need a mechanic/man in my life haha

You need to have your oil pressure tested with an oil pressure gauge to get the true pressure. It may just be a bad oil pressure sender. This will cause your gauge to fluctuate as if the oil pressure is changing, but the oil pressure is actually just fine. Post results of the pressure test and I will follow up.

Hi blueeeeee ok well my grand am is in the shop gettin a new oil pump lol but I wanted to pick your brain with another question. My son just got a 1991 Gmc jimmy and when I drove it tonite the temp guage was between half and three force to the hot side and wasnt blowing hot air from heater.I then went on highway the temp dropped and suddenly hot air came out of heater. Drove it about 25 miles then stopped briefly changed drivers and it shot all the way to overheating. We stopped to check it radiator cap was cool. Overflow was empty so we put some antifreeze in it and drove it awhile and the temp dropped again. Ok im thinkin thermostat but what baffles me is why when it overheats no hot air comes from heater? Do u think its thermostat or what ideas do you have?

Has all the signs of a sticking thermostat. If it gets stuck closed, this prevents coolant from passing through the lines. No coolant through the system means no heat for you and too much heat for the engine ;)

You can always remove thermostat and place it in hot water over stove. Use a meter capable of hot temps. To see what temperature it opens at. If it opens past around the 190F mark (or not at all) it needs to be replaced.
