my check engine light came on; I replaced gas cap (vapor link?); after some time being on, one day it goes off; the other day it comes back on; it has oil; car runs fine, no performance issues

The oil light comes on ehen I stop but comes off as the car starts moving

I put my car in drive it goes in reverse

When I start the car, the blower kicks on immediately and won't turn off, even if temp controls are off. I can adjust speed of fan, switch from heat to cool, etc... the blower just stays on.

I tried to start my car and it won't. I bought a new battery because the old one was bad but now it's not wanting to turn over. It's been sitting for a few weeks in some cold weather with low gas and I think the gas lines may be froze or my pump has failed. Any thoughts?

No crank no start just a clicking noise from starter once it starts it's fine till the next day

I have done everything under the sun but still get only warm. Thinking or going to change control valve to get more heat. The A/C condenser is white cold. I know it's to be cold but so cold it is frosted over?

What tools to use, basically what do I need to do. I get no signal through the radio, the car wash ripped it off. I have a new one, just want to do things right without breaking anything.

flushed heater core seems to flow normal. Cannot get warm air at any time, unless drive 50 miles. then get a little heat "HELP"

Water inside on passenger side but doesn't smell of antifteeze

Hello, I have a Mercury Grand Marguis 1997. I have been having an issue with my door locks working intermittently. When they top working, the key fob does not work, the switches on the door do not work and the remote trunk release won't work. I could get it to work sometimes by mashing the buttons on the door over and over. I found out last week that when I mess with my power seat buttons, (they haven't worked except randomly for over 10 years) that is when the power locks stop working. What part could be going out. The power windows still have power and the power side mirrors still work.

Thank you,
Carol

and my break lights are not working I changed all my fuses and still nothing I brought the parts the auto shop said I needed just need to know how much it usually runs to get it fix

My car while driving the headlights go out and it feels like the car is going to cut off.... when sitting still does the same thing but I turned it off and the headlights went bright but now my car won't start.... the battery clicks but that's it.... everything still cuts on except the actual car.... what could it be
