I have a 2003 New Beetle, I bought it for only 1k. So In expected some small things to be wrong with it, especially didnt think much would be bad since a mechanic owned it. Well, I have replaced both window motors and regulators, thermostat, the thermo housing. And some other stuff. The problem I am having now, the person who sold is to me said he just replaced the radiator. Well, the AC just stopped working, and my car started blinking the red overheating alert top right of the mph dash board. When i look under the hood the backup reserve/backup overflow is full, but im reading that it blinks bc the radiator needs to be filled. Does this mean its one of the hoses that are clogged? and its not pulling the liquid from the reserve? Sorry if i am not using the right lingo.. I have spent almost as ,much as i have paid for the car so far. I thought 1k for 136k miles was good for a vw.. But, I am hearing a lot of people tell me they are worthless at that amount of miles. The plastic upper interior piece cracked also when i replaced the regulator for the window, I was being gentle as ever. But, bc of the sun hitting down on it makes it brittle. But my main concern right now is, can i still drive it if it is no longer blinking and what should i start working on to keep if from over heating?
