Chequea que todos los cables y connectores no se mojaron de lavar el carro etc. y tambien que ningunas estuvieron quemado. No creo que esto tiene algo que hacer con la valvula de temperatura del radiador, pero si las electoventiladores tiran aire frio todavia, puede ser que hay un bloqueo en el "heater core". Tambien es una posibilidad que la pumpa de agua no esta functionando a 100%. Esa era el caso con una 1998 LS 400 que yo tenia. Que crees, que es problema electrical o mecanico(con la sistema cooling y radiator?

con respecto a la bomba de agua no creo pues los electros se disparan apenas giro la llave sin encender el carro ,en la maņana despues de haber pasado toda la noche apagado , yo queria saber si es posible que sea una seņal que manda la computadora o que ?

yo elimine la circulacion de agua en la calefaccion ya hace un aņo , pues aqui en este pais no hay necesidad de usar calefaccion , esta tenia una fuga ,pero no creo que despues de tanto tiempo esto incida en la falla que estoy teniendo

Hard to use the translators to interpret this accurately.

Check this as well as any vacuum lines. The loss of vacuum can create issues with other systems in the car.

He is having problems with his electric fans running when they shouldn't be, like before he even starts his car on a cold morning.

I thought it was the fan but also interpreted it as the heater blower motor and cabin climate control. With the heater removed that was my direction. Thanks.

As good as the translators have become, they still are challenging.

Gracias amigo
LScowboyLS pero la unica manera segun la tabla que tan amablemente me suministraste ,el encendido en alta velocidad se debe producir por alta temperatura del refrigerante , que no es mi caso , es algo inesplicable , por eso pienso si es alguna seņal de la computadora
