Heater problem
1998 Chevy Truck 6 cyl Two Wheel Drive Automatic

My 1998 Chevy (WT) truck's fan only works on low and high. My fan also makes a high pitched squeeling noise. I also hear fluid sloshing on the passenger side heater area and i'm loosing small amounts of antifreese but don't smell anything. What should I tackle first?

My 1998 Chevy (WT) truck's fan only works on low and high. ( you might check the blower resistor) My fan also makes a high pitched squeeling noise. ( the fan may have a bearing or bushing problem) I also hear fluid sloshing on the passenger side heater area ( either the heater core has a small leak or condensation from the evaporator isn't draining like it should, maybe both) and i'm loosing small amounts of antifreese but don't smell anything. What should I tackle first?[/quote:4eb52cf54a]
