After car warms up and I drive it for about 20 minutes I take my foot off the gas and the lights get dim and the heater starts to blow cooler air. When I push the gas pedal after a stop, the light brighten back up and the heat starts to blow warm air again. I replaced my alternator about 4 months ago. The research I've read suggests a belt or bad battery or battery terminals. Any suggestions?
