The Mother Board

[atsproperty]

I have traced a non working heated seat problem to the control module. took it out and its just a small motherboard. I can read M1305A and 84D41852Z01 Would anyone here be able to help me find a place to fix it or buy another one at a good price?

Welcome to Motherboards.org!
No results of a search for either ID numbers. Likely it is a specific part available only at a dealer that sells General Motors cars, but if more than 4 years old, may be an after-market item from specialty outlets. Or check local salvage yards. While a vehicle may be "totaled" from an accident, the electronics and other items may still be good.
Did find this link concerning the control module.. http://www.cargurus.com/Cars/Discussion-t26558_ds491955

Appreciate the help - I have seen that posted link myself and have posted questions there as well. Thank you tho.

In this case your probably looking at testing individual components to make sure they are not blown, burnt or faulty. I'd start with a volt and amp meter and work my way up from there. Failing that its probably not worth the effort to fix.

Ill have to find somewhere to get that done. Would you say a pc repair shop should be able to handle that?

they probably would, but they're going to probably charge a significant amount. my recollection is $50-$75 just to put it on a table and look at it. then an additional $50+ per 30 minutes of diagnostics.

if the board is simple enough they probably could figure it out in short-order. however, if it's simple enough then you probably can just grab a $5-10 meter yourself and figure it out with a friend that understands electronics.

i would check for local scrap yards, pay the entry fee to get in (if there is one) and scrounge up a few from busted cars. it'll cost you less i would expect than having somebody from a repair shop look at it.

Actually I'd bring it to a mechanic. They'll probably quote getting the seat replaced but at least your more likely to have it working.
Failing that try putting out a few feelers at local electronic stores (not places like Radioshack, but real ones like Active) maybe you'll find an enthusiast.

Some further browsing notes the seat heater module as part # 20806164 for GM products.. average retail price is over $300.00 USD!!!!!
But suggestions are to first ensure power flows to the module properly.. check if it could be a poor connection with a power socket/plug.. or possibly the thermal sensor lead or control lead, or a bad component on the module. The heating element should have no problem with burn-out, but do a series test with an auto lamp bulb similar to that used with back-up lamps.. the filament type, not the LED type. RV outlets have standard-base lamp bulbs in 10 watt and 30 watt sizes, at 12 volts.. and with a pigtail socket, make a handy automotive circuit tester!

Thanks for the advice. There is a burnt looking pin (not sure what to call it) and on the socket/plug in the same pin slot its smoke brown color. if i knew how to upload a pic here I would. I have a pic on this site http://www.cargurus.com/Cars/Discussion-t26558_ds535061?actionMessages=Your+answer+has+been+posted.
