Heater acting funny

[OverDrive]

Hi folks.<P>I no longer get hot air at the highest setting (4 for more air). If I set it at 3 it works <I>most</I> of the time. Also, at the 4 setting I hear a little noise (tinney rattle) coming from the passenger side vent.<P>Thanks for your time.

Possibly your heater core

Thanks for the reply. I was afraid it may be the heater core....big $$$$ to repair from what I understand.

I'm thinking its the switch or resistor

Yeah... the heater core is really expensive. It costs $500 CDN for a new heater core itself... aside from the labour charges! I know... I had to get mine replaced!....<BR>But your problem sounds like it may be the heater controls.... something to do with the switch.<BR>~Dean

Thanks for the replies.<P>In the on-line shop manual when it says "check for continuity between terminals of the fan switch" or "check for continuity between the terminals for the resistor" what does that mean exactly?<p>[ January 07, 2002: Message edited by: OverDrive ]
