Question about 1991 Volkswagen Jetta
I have replaced the battery, new starter, new plugs and wires. It continues to start hard especially after it's been running, I've stopped and try to restart. Sometimes when I am driving, the car loses power, not driving power but the lights dim and it runs a bit rough. Almost feels like something is grounding out. Then there's a horrible screeching sound, like a bad belt. Once the screeching stops, car drives fine again and has full power.
Sounds like your alternator is starting to seize up. Remove the belt and spin the pulley by hand. If you hear a light grinding sound or the pulley is stiff then the alternators bearings are worn. Take the alternator to an electrical repair shop for rebuilding. I usually pay around $50 as opposed to $100 or more from a parts store. Look up auto electrical repair in your Yellow pages. Older VW's are known for starter and alternator failures so finding a cheaper source for parts should help you save some money.
