Car Forum / Honda Cars / January 2005Heater blower activity affected by engine acceleration
'87 Honda Accord LXI Sedan (Automatic) with 200,000 miles. Still in great shape and runs well. More of a curiosity item than anything else - when the engine is running and the heater is blowing, the heater blows very strongly when accelerating the engine, but drops down when idling. I haven't checked thoroughly to see if other accessories are affected (interior or exterior lighting). Any ideas? Hi, Does your Accord have the original alternator on it? If so it's probably quite warn by this point. Typically a new alternator will suply sufficient current for the entire electrical system, no matter what RPM the car is at. However when they age, their output decreases slowly to the point that it is noticable. When you are driving, the alternator is spinning faster, which means it is capable of higher current output. I bet if you installed a new alternator you would notice a difference. HTH, -Jamie > '87 Honda Accord LXI Sedan (Automatic) with 200,000 miles. Still in great > shape and runs well.

Use some terminal grease to prolong the cleaning. Check body/chassis grounds as well. Also most auto-parts stores will test your alternator output for free... Thanks for the tips. I will have alternator function appraised. My battery shouldn't be an issue; I keep it in immaculate condition, and I just put a brand new battery in a few hundred miles ago (problem existed prior to that). |
