Guys I need some help

I have an 03 xr6T, about 110 kays. I recently serviced it doing an oil change, oil filter, air filter, coolant flush and refill.

Only mods are a 10 psi stage 1 custom tune, I always run the 8 psi stage 2 though.

After the service, the heater stopped working!! The fan works fine, A/C is fine everything really is perfect accept it will not blow warm air.

It was suggested that I 'burp' the system. Meaning I drain the system again and refill with the motor on and the heater and fan on full, in order to open the heater hoses etc...

Have just tried it this afternoon, no success.

Guys I could really use your expertise and advice on this one.

Thanks

I feel 4 u as I am in the same vote as u!!! When u swap btwn hot and cold, do u hear the motor whining? If so most likely air mixer shaft broken, dash out job to replace it. If u dont hear any motor whining noises most likely the unit called a HIM. This is expensive and connects to the air mixer shaft. Once again dash out job. Sorry to say. Just about all the cases, it is one of the parts. Dont be suprised if it starts working again..... if it does looks like faulty HIM

What do mean 'start working again'??

can anyone give me an idea of how much I might be looking at to fix this issue??

will it need to go back to Ford, or just any auto electrician??

thanks for the help guys.

Start working - the heat may start working again, it didnt 4 me, others it has.

How much - if u take it to Ford, shaft around $50 4 part, HIM around $500, labour grrrrrrrrr. U would get quoted over $1000 if it is the HIM.

If u do get it done and it is the HIM, suggest while at it to replace the shaft.

Others have done it themselves by pulling the dash out, depends on how handy u r.

Yeah its single zone.

even if we knew what the unit or the part we needed to change, looked like that would be a start.

good if we could have more input from the forum members.

No doubt there would be some boundless expertise amongst some of us......
