I have a 2004 Ford Focus I bought cheap around September. I used the A/C like once or twice but mainly used the windows as I preferred it driving through town.
One day I tried to use the A/CC again and it never turned on. Few months go by, it's winter and I'm sick and tired of no heat let alone defrosters. so I, having little to no knowledge of vehicles go to sleuthing about, and find the motor blower plug to be burned out.
I wiggle it around and get it to work, then I find my knob only works when turning to the left for selecting vents. Turns out it pulls a set of wires to change vents, and one is broken. I reach up under and turn the vents myself to defrost, thinking I just solved all my problems, I found I had little to no heat at all coming through.
I had no idea what to do for that, so I reluctantly went with sitting outside of work for 20 minutes while I waited for my windows to defrost using luke warm air, hoping I could make it home before it fully fogged up again (I usually did not make it home before fully fogged).
One day, particularly cold, I went outside and started the car ahead of time(expecting to be out of work 20mins from then) I did not get out till 40mins later. the cars thermometer was at the halfway mark(which is the normal operating temp for it since I've had it) and the windows I could see decently though.
On my way home (1.6-1.7 miles) the temperature started to rise, and by the time I got home, the overheat light came on, and the gauge had just hit red. I parked and checked the oil which was fine. so I went inside and talked to my grandpa, and told him about it and he suggested checking the coolant, to which I found was completely empty(there's no radiator cap, only the overflow) so I took my grandpas van and got a bottle from Walmart, and it took the whole bottle.
I assumed a hose was leaking, and I could hear it and steam spouting out when it got hot. I took it into bestone tire and had them check the hoses. They said they couldn't pinpoint it but it was def coming from either the head, or the block.
So I tried block sealant and it didn't work. Now I'm in need of a new car, but until then, I still need to use this one. Currently, I put antifreeze in when I can, but there's no telling how long it will last. I've had it sit all weekend and the levels change, and I've had the damn thing be empty the morning after filling it.
Currently I use it as my work vehicle, driving 1.6-1.7 miles to work and back, in town the whole time, but I don't know if I'll eventually find myself stranded or what.
I drove the car without coolant, overheat light came on. Mechanics said the leak is from the head or the block, but they're unsure.
