Air conditioner condenser and radiator fan stays on in 1999 honda accord

I had an accident with my car approx. 4 months ago (rear ended a pick-up truck) which resulted in the top pan being busted and radiator and condenser having to be replaced along with headlights, grille, bonnet etc. Prior to this accident my Air conditioner was working properly with the radiator and condenser fans turning on and off (cycling) properly. But after accident and having replaced all damaged parts including condenser and radiator both fans ran continuously whenever the a/c is turned on and never turns off unless i TURN OFF THE AIRCONDITIONER. However when the a/c is off the fans come on and turn off automatically as they should. I should also mention that the car operates at normal temperature and does not overheat. What do you think is causing both fans to remain continuously on whenever the Airconditioner is switched on?

It is normal (required) for the condenser fan to continuously run while the ac is operating. It is like that on almost every vehicle.

SOURCE: 1994 Honda Accord Overheating unless Heater is On.

Make sure your fan is working properly. When you turn on the heater you are forcing the fan to cool the radiator. It may not be turning on automatically when it is supposed to. Let us know if this helps..

SOURCE: 2001 honda accord, air conditioner is not working,

one fan is for the a/c it will cycle on when the a/c is turned on the other fan should be linked to the temperature sensor. check your fuses if you haven't already. then check your temp sensor. i'm not sure on a honda but most newer cars have multiple sensors so you will have to find out which on is for the fan. also you need to find out if the fan is controled by a pcm as some new model cars have almost everything controled through the powertrain control module

SOURCE: 1993 Honda accord radiator fan only runs after turning key off

You need to diagnose the car then let an expert work on the wiring system to correct it. This is purely an electrical fault. I tell you!

SOURCE: jump air compressor ac works replace relays same issue HONDA

the compressor may be low on freopn but, the fan problem is most likely the fan motor as it is the low temp fan and will run more often than both test see if you can switch the fan plugin to the other fan watch carefully that it does not get too hot as the second fan is a safety fan that works as high temp or when using the A\C

My 79 ford courier is leaking oil badly when it hasnt been driving and parked for days

Here is what you must do, pressure wash the engine and the transmission top and especially bottom of all grease and oil residue then install a bottle of special die that glows under a black light, drive the truck for a 10 or so miles and then put it on a car lift and check for the source of the leak with a black light. On this old of an engine the leak are likely all over the place.

Front end fender bender

out side of panel damage it will be the cost the of a new replacement radiator and labour-- about 1 hr . If you have damaged the condenser for the ac unit then it will be more expensive than a radiator and the time will be up to 2 hrs labour.

Radiator and condenser fans do not go off whenever ac is switched on on 1999 honda accord

The fans will likely come on with the A/C. One is to help cool the radiator when you aren't moving, and the other is for the A/C when there isn't enough airflow to cool the condenser. Both fans may continue to run even after the car is turned off.

Why does the Airconditioner condenser and radiator fans stay on and run continuously without turning off on my 1999 honda accord whenever the a/c is turned on? This started happening after I had a front...

Sounds like a micro switch problem.
the relay is staying and saying on even when off. An electric program test should fix the problem. They are small diagnostic machines that plug into a socket either under the bonnet or in/near the glove box.

Transmission slipping

Did you check the trans oil level. When you changed
the RADIATOR you will loose some trans oil.
If the transmission oil was low when you changed
the radiator it's lower now. Check it now.
Now, if thats not the problem. With that many miles
have you changed the trans oil lately theirs a filter
above the trans oil pan that may be pluged up change
it and the oil. Also, buy a can of trans X it's the only fix
in a can stuff I"LL use.

How many quarts of transmission fluid goes in a transmission

The Transaxle of the 1999 Plymouth Voyager:
(note: all references to quarts are US, not Imperial.)
4 Clyinder engine:
The pan holds 4 Quarts.
If you only drop the pan and not drain the whole system, replenish with 4 quarts. More than 4 quarts will result in busted seals and other problems.

6 cylinder engine:
The pan holds 8.5 Quarts.
If you only drop the pan and not drain the whole system, replenish with 8 quarts. More than 8.5 quarts will result in busted seals and other problems.

Only use ATF+4 in this transaxle.
Do not use Dexron or Mercon

Radiator fans not working .how do i know what to check and where on a 1999 honda accord ex

first thing to do is put multimeter in fan connector and check for voltage coming into fan through wire connector. If there is power chances are the electric fan motor in fan is shot. TRY STARTING FAN MANUALLY BY SPINNING THE FAN IF IT PICKS UP AND RUNS YOU NEED NEW FAN MOTOR
