Using Horn Stops Blower Motor/TCC Lockup Problem
Hi Boys and Girls,
I have a 1999 Bonneville SLE with 182k (about 70k on rebuilt transmission). Naturally aspirated, bone stock. Electronic climate control. I have a couple of problems:
-Weirdest of the problems - when I blow the horn, the blower motor stops but comes back on within a few seconds of releasing the horn. Seeming like a grounding issue, I checked the battery ground, both horn grounds, main ground near starter, both buss bars under carpeting, alternator (recently replaced) and basically wiggled every single wire I could find. Consistently charges ~ 14v. Headlights super bright; blinkers click fast as expected. I'm thinking perhaps a bad horn as I cannot come to any other conclusion.
-Second problem: Transmission lockup just quit. I'm going to buy a brake switch as I had a Grand Am that did the same thing and a new brake switch fixed it. As it is a $10 part, I'll crap shoot this one. Brake lights and cruise control work fine. Looking for suggestions here as well. Wondering if there may be some tie in with the blower motor problem. Might put in a new horn relay as well; another $10 part.
I appreciate any and all feedback on these issues.
