Ordering Relays

What to do next?
If you want to send in your GM III or GM IV for repair let me know. Contact me via email at scott@bmwgm5.com or call me at 310-283-4273 (do not text me) to check my schedule and arrange the repair. Payment should be made in advance via PayPal to account scott@bmwgm5.com or by money order shipped with the module. When you email or call I will give you the address to ship it to and let you know my schedule so that your module doesn't sit around while I'm on a business trip or on vacation or something.

If you don't feel comfortable sending a stranger money and your module you can deal with me in the eBay arena. I keep an auction going for a pair of relays. You can find me by searching for my user ID: BMWGM5. This way if you are unhappy you have a forum to let others know of your experience and petition to get your money back. Going through eBay does cost a bit more though. The higher cost is to offset the ever increasing eBay fees.

What's the turn around time?
I you paid for Express Mail next day return shipping I try my best to ship the modules back the same day I receive them. So, if you ship it to me next day air I will do the repair within hours of receiving it and get it to the post office before the 3:30pm Express Mail deadline. In this case door to door turn around time is about 48 hours. If you paid for Priority Mail return shipping, I will repair it and ship it back within 24 hours. All repairs will be done at an anti-static workstation by a competant tech. Unfortunately I won't be able to test it out after the repair, but, I will clean it and carefully inspect it under a microscope to verify that it was done correctly.

I want to do it myself and just need the relays.
I will sell them to you, but, I don't recommend doing this job yourself unless you are a competant solderer. The relays are very hard to get out due to the large copper area on the component side of the board and the use of lead free solder which has a higher melting point than the old tin-lead solder. Forget about trying to use solder wick. This is not an easy job and you risk damaging the board, plated through holes and having to replace the entire module at significant expense. With that said, the relays are $15 each with free shipping within the US and $5 shipping anywhere else in the world. Payment via PayPal is prefered. My account is scott@bmwgm5.com. Again you can go through my eBay auction if you don't feel comfortable dealing with me directly. My User ID is BMWGM5.
