i had a full tune-up and engine light came on and stays on, took it back had it reset, they told me it was internal, what does that mean, also oil sencor replaced too and after driving a bit when idle it comes on also. i paid 900.00 for mt repairs, i also relaced the AC motor

First off, I'm quite sure the catalytic converter needs replaced. I'm not sure if this would effect the A/C performance, but just recently the A/C stopped blowing cold air. After adding coolant, it works but only when the car is actually 'going'. When idling, it blows hot air. Then once I take off, it gets cold again. Also, I can smell the fumes from the catalytic converter and wonder if it being clogged might be correlated to the A/C running inefficiently.

I have a couple of friends who knows about cars so we could probably do it ourselves but what is the part itself cost

Nothing works and the windows don't come up. Gas gage, speedometer, rpm all are nonworking help

Bucket seat. Not power seat. Lift front handle and nothing. Was a problem of locking in place .now just stuck forward.

Shifter will not engage or lock into any gear. Have to use emergency break to keep it from rolling away. Just a big paper weight now. Thanks for your help.

So I bought a 2001 Pontiac sunfire as a beater car. The parking break doesn't work and usually this isn't a problem but because it is a manual I kind of need it. When I pull the lever the light comes on and it locks into place but it does not apply the parking break.

in the middle of the nite the horn just started blowing for no reason..car was locked and not broken into.. we pressd horn to stop the blowin and now it doesn't work at all.. I had brought it in and was told there was a short and that the whole horn pad assembly needs to be changed.. how does one change this without paying an arm and leg at a mechanical repair shop... my dad is familiar with car mechanics but is a lil older and hasn't wkd on Pontiacs...please help ... I found a used horn assembly to save money as I am a single mother ... he just wants to know the easiest way and to make sure he doesn't have to take apart dashboard and or go through hassles of motor..thanks in advance

idles rough taken to a garage they think it needs a new computer

I'm putting a motor out of a 99 s-10 into a 2000 Pontiac sunfire and had to change the plates to be able to put My coil packs on the head instead of on the side of the block. When doing so, I need to replace the casket and don't know what it is called. Thank you

The whole car rumbles while I'm holding the brakes and it's in Drive second or first what would be causing this

Ok so, I replaced all of the above. Before, the heat would get ice cold, the car would overheat, and if I loosened the cap, blackish water would shoot out of the overflow tube. Now, the heat always works, the car overheats a little, not as bad as before. I also get a very weird gurgling noise as well. It makes the noise when the car is running, and for about 15 seconds after I shut it off. If I turn my heat on, the noise goes silent, but then comes back, but not as loud. For an example of the noise I posted a video on YouTube. Please reply, any help is appreciated! I tried to post the link, but it will not allow me.

i had my father look at my ignition because he knows alot about cars but couldnt figure out what was wrong with it either. i also have to detach my battery because it keeps dying. ever since my ignition stopped turning my battery dies, wipers dont work,heater dont work and my sun roof wont open

How do I fix it?
