Have the dash out and I noticed that the foam tube that is connected to the temp sensor is deteriating (sp). This tube was replaced about 4 years ago. The heater in the winter was irratic. and the dealer found the tube was powder and replaced it. All was well then.
Now the tube is getting in pretty bad shape. So here's my question. The tube is only 4-5 inches long and connects a hard rubber tube from the temp sensor, to another hard rubber tube that goes to the blower motor, so it can suck the interior air through the temp sensor.
So why does this soft foam tube have to be SOFT FOAM?. I want to replace it with a harder rubber tube that will last more than 4 years in the Texas heat. any comments???????????
