Can anyone help with a heating issue? Sometimes it will blow hot and sometimes cold.

 

sounds like my wife.....as mentioned in the introduction section ...check for water under the front passenger side floor mat...you might have a heater coil problem

 

Roadman,

There is no water there. Kinda of thinking the blend door from other post i've read but still not sure

 

low coolant in the radiator is one of the main causes

 

Chrysler Tech,

The coolant is full. Anything else you can think of?

 

Header tank full doesn't mean there's coolant in the heater. It needs bled.

 

full in teh radiator not the over flow tank?

 

- we - the group might be able to help
- but diagnostically it would depend on what information we are given
- as yet you have given none, example, when does it it blow hot / cold ?
- example always cold unless heater turned to full, then its always hot
- means a lot, and points to a specific fixable probability to anyone on this forum
- so give us some info on when and at what settings it is variously hot / cold !

 

The hot and cold blows randomly regardless of the fan speed. I have it set on high heat.
