This is a great thread, was enough to get me started,
Here is what I did,
Used the search for Control Unit Solder to find this thread
Went to Home Depot and got the 25W soldering iron = $12.97 + Tax
Took the ashtray and radio out, the unit itself
Opened the plastic plate, examined the board and saw right away 3 bad points that needed soldering. I did about 6 of them in all.
Put it back in the car, WOW everything works !!!!!!!!
I have heat now !!!!!!!!!
Funny how much it matters when you are driving in a cold car freezing your butt off ....
Cool thanx for the help guys
