HI,

Sorry that you have not been helped yet.

HI,

Are the heater hoses getting hot
Customer: replied 1 year ago.

yes.

HI,

Ok, there is a service bulletin out for the blinking lights which involves chafed wiring. I have uploaded it for you

I would check this out first. If ok, then the climate control unit is faulty and will need to be replaced. But again, check the wiring where indicated in the service bulletin first

Sorry. Ive been busy with other ones. I did check for any chaffed wires behind where there would be a cassett bracket and i didnt find anything wrong there but i was having a hard time finding the one with the 6 wire connector to see if it was messed up. I did pull on the harness to see if it would make a difference but it didn't.

HI,

they are towards top of the hvac housing behind the dash. not easy to get to. But since wiggling/pulling on the wiring did not make a difference, fairly safe to assume it is ok, which leaves the control panel itself as faulty.
