Installed new blower motor, installed new resistor, fan would not come on. Put in a new relay, fan worked for maybe two minutes.
What could be causing the relay to go out?

It may be the blower is drawing to many amps causing the relay to go out or there is corrosion where it hooks up. Check for corrosion then use dielectric grease on prongs of relay and hook that makes for better contact. You can get the grease at auto parts for about $2.00 they have it on counter a lot of times.
