My 1998 chevy cavalier heater and ac does not work at all also the blower and fan does not come on and it keeps blowing the fuses

I would think either your fan motor is bust. Or it could be a cabling issue.

If you can access the fan motor. Think yours is accessed behind the glove box. Test the fan.

You should be able to get a replacement from a breakers yard.

If not the fan motor is could be a failed switch/speed selector.

Trying to find the relay switch to my heater on my 1994 Chevy 2500 Silverado?

There might not be any relay, Mary - it might be wired directly from the switch to the blower motor, although the lower blower speeds may go through a speed-reducing resistor pack to get there. If that's true, the resistor pack will be somewhere in the heater plenum, probably near the passenger's foot area.

If the blower doesn't run at all, check for voltage at the blower motor with a meter or test light, switch in all positions, keyswitch ON. The blower motor may have failed.

Blower will not work on high speed or on recirc but works on lower speeds.

Check connections on switch for loose or burnt wires.Sounds like it might a bad switch or blower motor resistor.Hopefuly its the blower motor resistor its cheap the heater control switch on the other hand is very exspensive. Make sure you check the wire connector for melted connection on the blower motor resistor this could be the has a new wire connector and resistor for alot cheaper than you can get it from anybody else.Hope this helps!!

At first the heater in my cavalier 2001 was working on everything but the first two speeds on the heater (low, and low-med), now only high works. The med-high does not work anymore. I can hear something...

With the lower 2 speeds not working, it was the blower motor resister pack that is bad. It is located in the blower motor housing which is way up in the front of the passenger side footwell. The part itself it fairly cheap (online ~$30, ~$50 locally [if I remember correctly]) and shouldn't take more than an hour to do yourself. The blower motor housing is held together by 3 or 4 screws, and 2 more that hold in the resistor pack itself. The worst part of doing this yourself is that it's in an awkward position for one of the screws. As for the rattling, it could just be something within the housing (you'll be able to check and clear it out of so).

'05 Freestyle Heater/AC blower only works on high(4). How do I get at the switch or blower motor. Everything is plastic! Does anyone have a solution? Thanks, Bob.

here is what my book says:
Blower Motor Speed Control To Remove:
  1. Remove the right lower instrument panel insulator.
  2. Disconnect the electrical connector from the blower motor speed control.
  3. Remove the blower motor speed control mounting screws.
  4. Remove the blower motor speed control.
