I have a cabin heater blower fan that is intermittent. With just the key on, ( 12volts), the fan operates normally. When the engine is started, (Approx 14.4 volts), the fan quits or operates very intermittently. The fan switch has power to it with just the key on and also with the engine running. The switch has been replaced, but I still get the same symptoms. All fuses have been checked. No other electrical problems. Any ideas?? Possibly a relay? Thanks for your input.
