95 Caprice Issues

[DirtyRedd]

I have 2 issues. My a/c blows cold air but my heater blows just as cold. What might be the issue. My second issue is both my front tires are worn on the inside. Does it mean I need an alignment or do I have bad ball joints? Thanks for the help in advance.

for the heat it could be that u just need a new thermostat or u could need a new heater core. Follow the top hoses from the water pump to the firewall where they connect to the heater core and feel them when the car is at running temperature. one of the hoses is supposed to be hot. As far as the alignment, you can jack one side of the car up and take a crow bar or long pipe and put it under the front tire and pull up on the tire. It should be firm but if there is play then the ball joint is bad.
