My heating system in my car stopped working, it just blows room temp air, AC works well, any body has any suggestions, also my car is collecting water in the bottom of the trunck during rainy day, suggestion how to fix it?
 
I've had 3 cars in which the heater would stop working when the radiator coolant level was low.

Check the coolant level. Make sure that it is full.

If it is, find the heater hose that delivers water TO the heater (usually located at the front of the intake manifold). Try to find a place near where the hose passes through the firewall to the heater.

Then find the heater hose that returns water back to the engine (usually at the water pump). Try to find a place where the hose comes out through the firewall.

With the engine warm, feel both hoses. If both hoses are warm, you probably have good coolant flow. It one is hot and one is cold, you don't have any coolant flow.

That if you don't have flow, the problem is probably a vacuum operated coolant shut off valve in or near the heater box.

If you have coolant flow and no heat, it is probably a vacuum operatued air diverter vane located inside the heater box that is not routing the moving air through the heater core.

Can't help you too much with the trunk leak (my '05-S doesn't leak) other than to run the garden hose over the trunk lid, then slowly and carefully open the trunk and examine the rubber trunk edge gasket and see where it is wet on the inside edge.

Good luck.

Get the garden hose and a small "friend". Have the small one get in the trunk with a flashlight. Run water around the trunk seal and have them look to see where the water comes in. One thought - also check the rear window seal.
 
:lol: :lol: Yeah, what he said! Otherwise you'll have to try and describe an unusual knocking and unknown banging noise come from the area of the car's rear end... LOL
 
This is not related to your forum. Have you ever had a ABS code set on this model ? I have a 2000, 3.0L and the code that it sets is the rear wheel speed sensor. I was wandering if you ever had any problems like this ?
 
I recommend you call a couple dealers and good indy's for their opinions. Bosch has had problems with the ABS controller used on several lines of cars, Audi/VW, LandRover, Jaguar, Volvo, where it would code for rear wheel sensor, but actual fault is internal in the abs control module.

Whether that applies to your model, I dunno. Need to gather info from those that deal with your model regularly.
